Exercise has never been easy for me. When I was young, I never understood why I couldn’t run and play as much as my friends. As I got older, I found out that this condition runs in the family. My mom and brothers also can’t sustain vigorous physical exertion. Some of my uncles and aunts on my mom’s side have that issue as well. Eventually, my brother found out that we have a mild form of mitochondrial disease, a rare genetic disorder. Luckily, it’s pretty mild for us and we could function normally for the most part. That’s life and we all have to play the hand we’re dealt. I still need to exercise even when I have some physical limitations. We can’t avoid exercise because things will only get worse as we age.
