Got Balaclava?

Balaclava As N-95 Mask:


I was just reading the new dose of sanity - that ppl should wear mouth, nose & face protection when in public in the US. To that end I just wanted to remind everyone, if you have a balaclava, you have the best possible face mask. There's no leakage around the edges, because there are no edges. A balaclava covers your entire face & neck.

I have both the Barrier and the Thermal  Pearl Izumi balaclavas, but in warm temps I prefer the Turtle Fur balaclava. Wash in anti-bacterial soap containing BENZALKONIUM CHLORIDE, or soak in alcohol, or probably, just leave out in the sun for 4-6hrs.

If you are headed for a high-risk situation you can't avoid, like taking someone to or picking them up from a hospital, you can tape a HEPA filter vacuum cleaner bag over the mouth with duct tape.

I suppose a cotton balaclava would be best, but that wouldn't be at all warm, so guessing nobody has ever made one. I guess you could boil it to shrink to fit tighter, but if there's any kind of elastic in it boiling it will ruin it. Ditto for bleaching.

When I ride, and I DID ride, ~ 100 miles last week, you can pull the hole down under your chin for unobstructed breathing. If you stop to talk to someone, pull the mouth cover up, and keep the wind blowing BETWEEN you, so whatever comes out of your mouth or their gets blown away by the wind.

If you ride in a group you'll be inhaling the breath of everyone in front of you UNLESS you have a crosswind. I'd RX a min of 20ft of distance between riders if riding in a group, and practice rigourous pace-line rotation to min the risk. When in front you should be in clean, sterile air. Not so much the further back you go. Line up to get a crosswind between everyone when stopped.

Up here at ~ 3,000ft the sun is roughly 30% more intense, so that and a strong, dry wind make it hard for any micro-organism propagated in a water droplet to last long, but the best protection for me as a rider is there are plenty of places to ride where you won't see a living soul, or perhaps one just in passing.

When passing a rider, assuming a closure rate of 30-40mph, that's  ~ 50ft/sec, so you'd be in a "danger zone" for ~ 1/10th of a second. You aren't going to get much of a viral load in a tenth of a second, and if you and they are healthy enough to be out riding at that pace, not much chance of infecting each other with ANYTHING.

This is more true when there's a crosswind, because then the "window" is narrower than 5-6ft. With head or tail winds you might want to hold your breath for a few seconds just as you pass, but still a very tiny chance of getting infected by anything.

Cologne As a Distancing Indicator:


I was riding down Apple Valley Rd here and came up behind a ped up-wind of me in a 25mph wind who was wearing a ton of cologne. It occurred to me that if you can smell someone's cologne or perfume you're probably getting too close. I did, for about 5 seconds but the wind still mixed a lot of fresh air with his breath.

Do consider wearing cologne when on a group ride, and explain the logic of it to the rest of the group. This idea could be a break-thru in public health. Maybe someone in the group could bring a spray-on bottle to share. Rotate that duty.

Be safe, and exercise to stay healthy!

PS:
Dead Wrong about no cotton balaclavas. Tons of them out there - some as cheap as $3.00. Just Google it. This will scare the crap out of the kids!

Killing COVID-19


In my last post I made a claim that BENZALKONIUM CHLORIDE probably kills COVID-19. I am happy to report that I have found solid confirmation of this claim by the Canadian Government.


Benzalkonium Chloride kills COVID-19. It's found in most common antibacterial soaps. This was also very interesting to me, confirming that corona viruses are actually EASY to kill. 
Coronaviruses are enveloped viruses. This means they are one of the easiest viruses to kill with the appropriate disinfectant product when used according to the label directions.

Walmart's house brand Anti-bacterial soap - also  kills COVID-19

Note that hydrogen Peroxide (typically a 3% bleaching agent), "bleach" (sodium hypochlorite), alcohol and the ingredients in Clorox's disinfectant wipes are in the list too. Usually, a 50% solution of Ethanol (not commonly found, except at drug stores) is as effective as 60% Isopropyl alcohol, so look for ethanol if isopropyl isn't available. Bacardi 151 should work beautifully! :)



 Chlorhexidine gluconate also kills COVID-19. Worth noting here, chlorhexidine gluconate has a wonderful property, unlike most items on this list which kill almost everything on contact, it soaks into your skin and continues to kill for up to 4 hours - which makes it my favorite road-rash soap.Walgreens sells my favorite version of this soap as it's cheaper and smells better.

Optimal Immune System Support


It's been 10yrs now since I dipped a toe into the "Smoothie" craze, and it turned out not to be a craze with me at all, but a fundamental way of getting excellent nutrition to reduce inflammation and optimize my immune system. To that end I am posting my smoothie recipe, which has evolved a bit over the last 5 yrs.

The basic recipe, which has been stable for the last 10 yrs is...
  1. Spinach stuffed down into the bottom of the blender & packed tight
  2. Florida's Natural OJ with calcium & vitamin D, poured till just over the top of the spinach
  3. Dried cranberries sprinkled over that - about 1/2 a cup of Mariani's
  4. Wyman's wild blueberries to the top of the blender jar, 2-3 cups
  5. Bananas, 1-2 for sweetness, creaminess, and potassium
Wild blueberries are smaller, so a greater % of their weight is skin, which is were everything good in blueberries (and almost all fruit) resides. Any wild blueberry brand will do, but Wyman's is pretty universally available here in California. Bananas are pretty much a sugar cube, but also stabilize the Ph of the mix and add a nice creamy mouth feel. After blending you should see tiny bubbles rise to the surface. This is the calcium in the spinach or kale reacting to the vitamin C and other acids in the fruits. Without this acid the human body cannot absorb the minerals in leafy greens (or from any other source for that matter). Use whatever brands you prefer, I just wanted to be specific about what I use.

There is one variation on this basic recipe I have used for years. When strawberries are in season, and the price drops below $1 a pound, I love to add strawberries & kale, the kale in place of part or all of the spinach. Strawberries & Kale go together like PB & J, and provide a nice change in the vitamin profile. Everything else stays the same.

I made an addition to the basic recipe 5 yrs ago when I ran low on OJ and had some POM on hand. I added a cup of POM in place of OJ, and that change definitely and firmly put my smoothie in front of any amount of Ibuprofen for controlling swelling, and the aches & pains I felt the day after a ride. I have also tried POM stand-alone, and it didn't help much, so it is in combination with the antioxidants and anti-inflammatories of everything else that it works well (EVERYTHING in this smoothie is a very powerful antioxidant and anti-inflammatory except the banana).


About a two months ago I decided to try adding Elderberry to my smoothies after trying the gummies and noting yet another reduction in swelling, aches & pains after riding. Typically on days I ride I take a gummie an hour before and immediately after rides, but I'm also adding 30-50mg of liquid Elderberry extract per serving to my smoothies now, and that has again improved the mix, so add to the basic recipe...
  1. Pomegranate juice. I prefer Bolthouse's brand, but POM is excellent as well
  2. Elderberry juice extract, 50mg per smoothie serving
 AFAICT, everything that is an anti-inflammatory is also an antioxidant, and immune system booster, as inflammation is a root cause of immune system impairment and cancer. Linus Pauling won his 1st Nobel Prize for work in this area, and later put vitamin C on the map by speculating it could help boost the immune system in humans.

Just to be clear, an antioxidant prevents oxidative damage to tissues, like the large skeletal muscles that power cycling, which is the nasty side-effect of metabolizing carbohydrate (blood glucose) in the Krebs cycle by oxidizing it. If you're making watts, you're making free radicals, which are the product of oxidative damage to tissues. Thus, antioxidants should be used while on the bike. To this end I now add Emergen-C to my Gatorade when I ride. Berry Blast Powerbars used to include many of the same vitamins, so this just makes an "Enriched" ride fuel now that it's impoverished. If you can afford it, you can also mix Acai juice 50/50 with Gatorade. I Googled "does oxidative stress cause cancer?" and got this...
"Oxidative stress is likely to be involved in age-related development of cancer. The reactive species produced in oxidative stress can cause direct damage to the DNA and are therefore mutagenic, and it may also suppress apoptosis and promote proliferation, invasiveness and metastasis."
Anti-inflammatories prevent inflammation primarily after a ride, and also help heal joints and tendons in conjunction with calcium, magnesium and zinc, which leafy greens contain in abundance, even if they weren't readily available in supplements. It's very convenient that berries, apples, chocolate, turmeric, etc (see chart below) meet both requirements, so only the timing of consumption changes, and morphs roles seamlessly from during to after riding. It's worth noting that most of the compounds in my smoothie, have also been shown to reduce the risk of cancer.
"Indeed, cancer initiation and progression has been linked to oxidative stress by increasing DNA mutations or inducing DNA damage, genome instability, and cell proliferation [11]."
In the last 15 yrs the health benefits of berries has been studied extensively, and the compounds in their skins almost all have health benefits to humans. The USDA published the potency of these until it was abused by sellers of all kinds of supplements and they decided to stop publishing it. Fortunately, I kept a copy I can share.



Honorable mention to two other juices, Acai and tart Black Cherry. I prefer to drink Acai by itself, but the cherry juice is pretty bitter, so that goes in my smoothie from time to time.

My initial recovery food just after a ride is mashed potato, freeze-dried Idahoan brand of late, as it's quick & easy, but a large russet potato washed and microwaved is also excellent, cooking while you shower off, and until recently my preferred post-ride meal. Potato has lots of vitamin C, and is the richest natural source of potassium, but it's also near 100 on the Mendosa Glycemic Index, so it has the fast carbs needed to prevent catabolic muscle destruction by inducing an insulin spike. I use lots of Kerry Gold grass-fed butter too, which is full of Omega-3 fatty acid - also an anti-inflammatory - along with a glass of organic grass-fed milk. All animals, whether milk cows or salmon fish, get their Omega-3 fatty acids from plants - either grass or plankton.

After 30-45 minutes I've had enough time to digest the post-ride carbs, so time to drink my smoothie, usually two 20oz servings in the first few hours.

I decided to write this post after seeing a few stories about boosting your immune system to ward off the COVID19 virus. I think you're going to be hearing a LOT more about Elderberry.

PS: If you're here to bone up on managing COVID19 exposure, you should know that common anti-bacterial soap is also anti-viral. Although Benzalkonium chloride has not been tested against COVID19 specifically, most viruses are pretty fragile outside of a warm body, so a good bet it will also kill COVID19.

"Benzalkonium chlorides (BACs) are chemicals with widespread applications due to their broad-spectrum antimicrobial properties against bacteria, fungi, and viruses."

Risk Mitigation 101 for Cyclists

At least in California, highway funds are allocated based on how heavily they're used. This means heavily traveled roads - main roads and their feeder roads - get the most money, are the most well-maintained, and typically have paint and signs "protecting" cyclists.

The record is clear though, paint and signs don't protect cyclists, only physical barriers do. Dot-Bots and rumble strips help some, but paint is pretty worthless. I've seen dozens of violations of the cyclist lane on random afternoons in less than 5 miles. It's just a matter of time before a cyclist is hit when this occurs.

The question then becomes, what happens when a cyclist is hit? That depends almost entirely on how fast the motorist is traveling. These numbers say loud and clear, stay off heavily traveled roads with fast traffic if you value your life. These numbers are for Peds, but 15 lbs of carbon, and 12oz of Spandex aren't going to make much difference.


If advocating for cycling infrastructure, please point out that where there are discretionary funds, those need to be spent contrary to state transportation funding guidelines to create "Light Wheel" infrastructure bearing 300lbs max instead of 200,000lbs max. The cost of a bike trail is roughly 1/1000th that of a freeway lane.
