Thanks so much for the story! This is why I posted. Your ordeal was so bad that I’m ashamed of myself. LOL
I’m 64 but I’m extremely active and I’m only 120 pounds. It’s rare for me to sprain an ankle or anything else because of my leg strength. I ride a mountain bike on gravel/dirt trails in the mountains 20 miles at a time. My size is probably the main reason nothing was broken. My daughter has broken one foot three times and she said the time she tore ligaments with the break was worse that the other two breaks combined. I guess that’s why my doctor laughed when I was relieved it wasn’t broken. He laughed and said breaking it would have been better.
At your age, 64, I had a quadruple bypass and valve repair open heart surgery. Died in intensive care two days later but was miraculously revived after they cut my chest opened again and hand-massaged my heart beating back to normal sinus rhythm. I spent five weeks in the hospital instead of the usual 5 days after heart surgery. It took me over three years to recover from that.
I'm fit again and like I said, I work on a farm and am very active. But being in shape is no guarantee against injury. I liken getting older as being permanently injured. The aches and pains never go away.
You're best to accept that you're getting older. So enjoy your bike rides but don't push it so hard. At your age, it won't add any years to your life anyway. Fate has already set the date for your demise. Trying to exercise your way out of it is futile at this juncture. :-)
