I'm extremely suspicious of xray machines at the dentist and the doctors office. I refuse any xray that isnt absolutely vital. Medical professionals do them as a box checking exercise to prevent mal practice law suits, but they are largely useless. They do catch issues, but if you are young and healthy, the radiation risk is definitely there.

Another reason to be more injury avoidant than most young people usually are! I have lots of friends who sometimes have to go to the doctor for a sprain or hairline fracture or something, often from sports. It just doesn't seem worth it to do stuff like volleyball or any high impact sport.

  Fractures are very rare in volleyball. High impact sports such as weightlifting are critical for bone health and building skeletal muscle. Lack of bone density and insufficient muscle are certainly more dangerous than an occasional x-ray. https://peterattiamd.com/ama37/ https://peterattiamd.com/ama37/ I do agree with avoiding sports that have a high risk of concussions due to head impacts.

    Lots of people seem to make it to old age, still being almost as healthy and active as an average young person, sans any broken bones, without lifting much of anything heavy or playing any sports, they seem to just do causal swimming or hiking or tai chi or something. And there are gym rats who have a life of all kinds of random aches and pains despite being very strong, then have heart attacks, so I'm super confused on what you're actually supposed to do, but it definitely seems like there's a limit to how much people really need for close to optimal health. The science seems pretty clear that having muscle is better for your health, but it seems really hard to figure out how much is actually needed, and whether someone who's already reasonably in shape from walking and doing projects actually needs any lifting outside the "near zero injury chance and you probably won't be sore tomorrow" range for maximum health issues prevention.

      There is certainly a genetic component to bone health, but on average most people aren't able to build up enough bone mineral density and skeletal muscle without lifting heavy weights. You're dreaming if you believe you can get in shape by walking and doing some casual projects (heavy manual labor is another story). Beyond a certain age it becomes essentially impossible to build those up, and then you start gradually declining year by year. Do you want to spend the last years of your life crippled because you fell down the stairs and broke a hip? In order to figure out how much muscle is needed, decide what you want to be able to do when you're old and then work backwards from there. https://peterattiamd.com/how-to-train-for-the-centenarian-decathlon/ https://peterattiamd.com/how-to-train-for-the-centenarian-de...
