I have not experienced any broken bones, except for a broken nose in a car accident when I was 15 when my mom was driving and a fractured knee from falling down concrete steps when I was 23. I just need more recovery time now. I've always needed more warm up than others and over exercising /overuse injuries kept me sick with infection after infection (respiratory), plantar fasciaitis, and a stress fracture in my 30s. I also weighed 92 pounds.
Yes, I learned my lesson, but it is still hard for me, even though I know better. It's a struggle to take 2 rest days a week, but I really need to. I want to do more and get faster all of the time. The problem is, it's really hard to do this at my stage of life! And, I know a lot of people from my cycling group, who are 5-15 years older than me, who do a lot more. I have a hard time accepting aging and I dislike people who "embrace" their oldness. Some of my issues are from my own peculiar health issues that I have struggled with off and on since I was much younger. But, I still keep at it and it helps to surround myself with others who are extremely fit.
