Anyone Else's Body Feeling Old and Slowly Falling Apart?

I didn't think I'd start getting old at the the age of (32). Last year my back gave out during deadlifts (never doing those again) and my neck issues flared a lot. Mri showed that I have some mild things with a few disc's between both, but I believe I have more throught my spine. This year I'm still working on healing both with at home care program, no gym still (13 months). A lot better than last year. But now pain in both legs below my knees. I guess this is the start of getting older with all these different types of body pain and issues?
