I also think that the older I get, the more “being healthy” becomes a primary motivator. I’m not like a 20-something looking at maybe developing arthritis or heart disease or alzheimer’s at some not-quite-imaginable time 40 or 50 years in the future. I’m (statistically speaking) looking at it surprising me like a jack-in-the-box in the next five years, smack in the middle of my remaining productive life.
All I can say is I wish I’d had a bit more concern about this when I was 20, but I know that’s not totally realistic, 20 was a time filled with other issues! Nevertheless, if your only issue right now is weight but you put your imagining cap on, you might see how nice it would be to hit 50 or 60 knowing you’d done everything possible to avoid chronic western disease.
