My brother was a self-employed tile guy in Spring Grove, Illinois. He made good money, and he has some nice toys, but at only 64 years of age his body is a mess. When he was about 50 he tore the rotator cuff in one shoulder, and then he tore the other a few years later. He’s had multiple surgeries on both shoulders over the years, but the end result is that now he can barely lift a gallon of milk with one hand/arm.
