It really is. I'm up and down ladders all day, and had a major ankle/leg surgery two years ago after a bad injury with three fractures & dislocation.
Glad to hear you're feeling a bit better, and I hope you do well in school!
I feel like I've only heard about that in passing, I'm not super familiar with it or how it works.
That's a good stance to take and will probably add several years to your life. Alcohol is pretty much the devil in my eyes.
