The first three mechanic shops I worked in I was the only mechanic. And that taught me early on how to be strategic in how to lift and move heavy things. I also came to the realization there would not be anybody find me for a while if I did get hurt. So it just became how I approached things and it was lucky because later it saved me from hurting myself bad. Meanwhile my brother who's two years younger has had his neck fused, his lower back fused and rotator cuff surgery on both shoulders. He is in constant pain and basically disabled. I am scared to death of doc's and his exoerience reinforced that. But last year my wife who's 5yrs younger had hip replacement and is doing great, better than before.
Two of the best back savers in my shop are a 2ton folding HFT engine hoist and a 1,000lb lift table. I've had the hoist/cherry picker for 10yrs and it mostly is in storage out in my shed. But it has saved my bacon so many times I can't count. The lift table I wish I would have bought years ago too. I mostly use it as a welding/fab table but it's proved it worth so many times I can't figure out why I waited so long.
