Lifting for the Long-term

Anytime I go around family, they hate on weight lifting. I have one relative who swears by these work out(rubber) bands for strength–“If I would have done this years ago instead of lifting, I wouldn’t have gotten a hernia.” I’m a fan of lifting, so I generally don’t care about what the haters say. I think most haters work out for a few years and get an injury due to bad form. Then they become the armchair sages on lifting. I’ve gotten dinged up over the years, but I’ve always been able to recover. I’m 35 and lift 3 times per week–4 compound/2 single-joint exercises. My question is, how have lifters aged 35-70 adjusted their program to avoid injuries and promote long term health?
