Hang in there. My Dad fell off a 16-foot ladder when he was 80, broke all ribs, punctured a lung, got a concusion and was in the hospital for a week. Everyone said he would never be the same. A year later he was up and running like new, except for a drooped shoulder that looked funny but did not seem to affect him. Yes, it takes more time to heal when older, but you do heal. Good luck.
