And while I agree that taking care of one self is important, I want to touch upon a more fundamental point. I am perfectly OK with taking rest from time to time, or taking it easy, or just sitting back with my feet up enjoying a good book, or a glass of wine with my wife. There's in my opinion little need to always be on 100% and it's perfectly OK if people aren't. I know this opinion is like cursing in church on this forum, but many people would do well being nice to themselves a little more.
That's freeing in a way, it tells me that when I feel pressed for time it's really all in my head and taking an hour to read a book shouldn't be a problem if I just take a few minutes and prioritize my time.
Also it's probably useful for some people to see how much time is spent on work and commuting relative to other parts of their life. If they truly have no time to read a book but work+commute is eating up more than 50% of their days, maybe it's time to do something about that and fix one or both parts of that equation (move closer to work or change jobs to get closer to home, and work fewer hours)?
Then there is (on top of above) the vitamins / minerals category, in which I was shocked to find that most supplements out there are in a form that doesn't get used by the body. Sorry, no english doc here :(
Addressing my various food intolerances - it's very personal and it's more about the process. Experimenting with avoiding gluten, milk, egg (for me). Try-and-repeat. Be consistent (this was the hardest for me).
And fighting my constant virus load - again, very personal, but these ones that work for me, using in combination: lactoferrin, grapefruit seed extract, ganoderma lucidum mushroom, propolis drops, and one I won't write down on HN because I get downvoted for it... :)
