Just an opinion, mind you....
Europeans get huge vacations. 4 weeks per year, I've heard, is mandated in some countries. Me, most of my working life, I was lucky to get 1 week per year. My last job, I had 2 weeks per year. But when I was laid off, I had almost 3 weeks saved up. Why? I couldn't find the time to take a vacation. We were severely understaffed, since corporate was too cheap to replace workers who quit.
Okay, getting back on topic.
Me, I'm about, I dunno, 80 pounds overweight. When I was a kid, I tended to forget to eat some days, but I still was fat. I think my body went into survival mode, and when I don't eat, it starts storing fat. In addition, I tend to eat a lot of starches, and definitely a LOT of processed food. (Frozen dinners, for instance. I can't cook.

)
I can't exercise, because I was born with bad knees. They're not connected right. The tendons have a tendency to try to pull my kneecaps out of their groove when pressure is applied to them. So, I had to finally give up riding bikes when my knees were going through excruciating grinding sensations. Fun!
In addition, I've a tendency to sprain my ankles. "Keep off them for a week," I'm told. Right. I went to a college that was spread out over ACRES of land. (University of California at Davis, a huge university.) I would have to get from one end of the campus to the other in seven minutes, the time alloted between classes. Couldn't wait for the little golf carts they used to ferry people with casts and crutches. One week, I sprained both my ankles, stepping into potholes. Another time, I was taking a moonlit walk around the Arboretum (a big "lake," about 9 miles circumference, surrounded by trees), and the path narrowed in an unlit area. Crack! I stumbled off the path, sprained my ankle, and had to walk about 8 miles on a sprained ankle, or sit in the cold for 8 hours until someone
might find me.
Then, at the place I worked before my last job, I had a bone dislocate in my foot. For
two years, I could barely stand up, much less walk or jog. It's better now, but now I've done something to a tendon....
Basically, it comes down to: Does anyone have any spare body parts they want to donate?

I'm only 32 years old, for goodness' sake!
