@jamessaxo I don't consider never being drunk off of my ass, or behind the wheel of a car to be a sad thing. It was a choice to not follow in the footsteps of some of my co-workers throughout the 80's who spent huge amounts of money on beer on a daily basis.
I made the choice to not consume alcohol before I was even old enough to drink, or ever touch illegal drugs. I've never been drunk or high on anything other than caffeine. Even if I had tried to consume alcohol, everything I ever tried in my youth tasted like crap, so I wouldn't have been a drinker anyway.
As for vitamin D, I've taken an adult multivitamin every day for decades. My doctor says my bloodwork is always great.
