If someone tells me kale is carcinogenic imma lose it because it does not taste good. I’m not eating this for fun you know.

Have you only tried it raw? There are ways to cook it without losing too much nutrients. Cooked kale still has noticeable health benefits according to some studies I found.

Raw or cooked... the only way kale tastes good is when it's the garnish on a steak that gets thrown away at the end of a meal.

I really want to know, why don't we all supplement with L-arginine long term? Time-release capsules are available and I have taken for numerous issues like RSI to great success. Whats the downside to long term usage?

Arginine has good short-term endothelial effects but bad long term effects. Most studies last https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4069264/

I took beetroot as a supplement, it worked well. Ginkgo Biloba also increases nitric oxide. I've had negative effects from strong antioxidant supplements before. I think there could be a lot of reasons why.

Combined flushing niacin with beetroot did wonders for me.

I'd like to add(0, •) another item to your list: 0. Stop mouth breathing and do nasal breathing whenever possible because only the latter produces nitric oxide, see https://en.m.wikipedia.org/wiki/Biological_functions_of_nitr...

The older I get the more ways I find out that mouthbreathing is harmful. I wish someone had tried to do something when I was a kid.

I’m not sure what the proper name is for this idea, but I consider ageing to be a trade-off between cell-regeneration, which maintains youthfulness, and mutation-limitation, which reduces the chances of cancer. That is to say, if you “aged less”, you would get cancer more/sooner. Everything else, like the balance of chemicals in the body, I assume would be downstream of that.

I'm not a biologist, but I believe what you're talking about is telomerase?

Telomeres are just repeats at the end of chromosomes to allow for replication. They aren't directly involved in replication fidelity beyond allowing for replication to proceed. I guess protecting genes near chromosome termini but that's different than the mutations you would expect in cancer.

You should try it southern or soul food style similar to how collard greens are cooked. It’s cooked along with meat and a bunch of seasonings. Definitely a different flavor. But also less healthful.

Exercise tends to help.

My kids have started taking swim lessons at the Y, so i've been sneaking up stairs to run a mile during their lesson. I've thought about strength training etc, but I have no idea what i'm doing on those machines. Can't say I feel any different, but it is enjoyable.

Pretty much anything that makes your muscles feel sore and doesn't cause injury is worth doing.

IMO: most of what makes fit people fit is becoming aware of their body in detail: how to use muscles, how they work, what they feel like, what they should feel like when they're working together -- all of this builds a foundation where, if they lost their fitness, they would just get it back again.

So if you don't know what you're doing: just learn by doing. Pick something that it seems like your body should be able to do easily, but can't, and fix it. Repeat x100 and you'll be fit as hell.

Floss once or twice a day, maintain gum health, and watch your diet. You don't need mouthwash. (Anecdata - at my most recent visit, my dentist told me to come back in 18 months.)

That’s strange for your dentist to give up money like that lol. But also, at dental cleanings they do things like polish your teeth. Do you also not require that?

As it was explained to me, flouride will work in repairing microscopic areas of decay so long as the surfaces of your teeth are ultra clean.

My dentist insists that I see the hygienist every 3 months for descaling, cleaning and basic checks.

For the cynics, the cost of this is negligible and I have not needed a filling or any other costly procedure for over a decade.
