Good news and bad news
First the bad news. Many present Americans are obese, like overweight and can’t even qualify to be a private in the military. That all too often applies both to males and females, too. Said another way, they are not acceptable to fight to defend their own way of life as it exists today. Now not being "acceptable" is a harsh judgment, but most often to the advantage of those affected.
Now the good news. Being obese may have advantages for a short period of time if hard times should come. Having some “plump” on should help survive if hard times should come upon us.
