We need to think about these things when we are younger and older. I tell all my patients that are in their 30's and 40's that the small pains and irritations left unchecked now become bigger problems in our 50's and 60's, arthritic and degenerative problems in our 70's and disabilities beyond. This is not a lost cause if we have already reached some of these ages as we can still be pain free even if we do have some degeneration, arthritis or accumulated damage. It just takes more effort and consistency with our corrective measures.
Take Away: Pain is not the normal human condition, don't "have a high tolerance for pain." If you are suffering get help in some form. Move more. Eat better. Sleep better. If you find ways to do that I promise you will Live Better.
