PT is for real. At around 50 my mom put down her Harley sporster and broke her right arm into 7 or 8 pieces. She failed to do the prescribed PT and I now tease her about her T Rex arm. She can't lift the right arm above shoulder height and can't reach more than 2 feet max.
Not saying she would have had like-new results with the prescribed PT, but almost certainly better than where she is now.
