If the body deteriorates, then mind follows. You're fat, ugly, out of shape, the girls won't talk to you, the guys (as best) will use you as 'practice' with zero love,......then you get bitter, angry, depressed, 'fuck the world', wear lulu-lemon yoga pants 5 times less than your size when going shopping at Wal-Mart wishing/deluding yourself to still be desirable to someone, and then get snappy with petty requests like, 'I wanted extra-pickles on my cheeseburger you dumb wage-cuck!" making your outrage a highlight on Worldstar.
Same is said for the mind, if that deteriorates, you get depressed, angry, bitter,...you don't want to move, so you're never physically active anymore, drugs and alcohol is used as a crutch which also affects the body. McDonald's and other high-calorie foods makes people happy... then the body goes.
Your second paragraph makes me imagine funny pictures in my mind.
