I hear people say this a lot, and I used to believe it, too.
Then, I changed my habits and figured out how to be healthy.
When you really think about it, how do farmers do it for so long? What about master martial artists?
There's all kinds of examples of people advancing in age yet being fully capable still.
Stop believing it's inevitable to be broken as your age goes up, and you'll stop being broken all the time. Your body breaks down when you don't use it correctly and don't take care of it.
Learn to treat it right, and it'll treat you right.
No excuses!
