This is false. As a person gets older, the physical changes that they experience from aging would make them more vulnerable and prone to injury. This would be because as a person gets older their muscle mass decreases (it gets harder to maintain), their bones become more fragile and along with the fact that their reflexes aren't as good as when they're younger. So when they encounter a situation that requires fast reflexes in order to make it through with little to no injury, they wouldn't be able to save themselves from getting injured easily.
