I would say the problem is people are stuck spending most of their time and especially energy on #1 just to make ends meet. Obesity, like drug addiction is a disease of despair, and we have a lot of that in our country. Also, the longer you live, the more beat up you get. Taking care of elderly parents, dealing with shitty bosses, shitty partners, etc. It definitely takes a toll over long periods of time.

I've recently made #2 my top priority due to an eye-opening, but fortunately reversible doctor's visit recently. When the priorities are lopsided as mine were, it takes twice the attention for #2 to get balanced than to maintain the balance. I'm making decent progress though. It will take at least a year to remedy.
