I'm not sure why you'd equate "some weightlifters sometimes have red skin" with "my cousin sometimes got red skin and he died" with "vegan yoga is good for you."
Veganism is associated with a slew of health problems.[0] But regardless of that, the first two statements are completely unrelated. Weightlifters don't naturally have higher blood pressure, and lifting weights regularly lowers your blood pressure, it doesn't raise it. I've seen the flushed, red, vascular look you're talking about. I'm sure in some people it's natural due to low body fat and I'm sure in some people it's a combination of pre-workout and creams designed to give exactly that look.
> Veganism is associated with a slew of health problems.
As compared to what?
Yes. You can’t get B12 on a vegan diet. Vegans supplement it.
Side note about B12: a B12 deficiency from a vegan diet largely comes from environmental sterilization. B12 is bacteria-produced. You could drink stream water and get your B12 “naturally”, too.
To some degree I do believe people can spot health problems in other people.
After all we do chose mates and assess their overall health based on looks.
In terms of longevity, I feel there's probably some minimum amount of exercise you need to do, after you might be better off at addressing other things if you have other deficiencies. (dental health, snoring, etc)
Thinking in terms of a sports car. You can do all kinds of things to maintain and improve the engine. But if you want long term success, don't forget about the breaks or other systems that might need take you out a lot earlier.
