Looking after myself alot better now.

I’m in the same boat. I started to turn things around in my late 20s with regular exercise, and my knees (and back) feel better at 31 than they did at 25.

It gets worse. Take care of your body

Until you sport too much and get an injury, and then it’s just a chain reaction of things breaking down because you can’t exercise them like you used to.

I’d say workout, yoga, lift heavy thing.

Sports only if you actually enjoy them. Most people I know heavily into sports get injured and some of injuries do not heal back to 100% ever.

I think the issue is that if you had injuries at younger age, those injuries become inflamed again as you become older. There are athletes who said their injuries become inflamed again when they hit 30’s. There are also soldiers who passed away after their old wounds became a problem again at old age. The body just can’t keep up repairing itself anymore.

However, old injuries isn’t just the only explanation. If one have hardly been sporty or did labour intensive jobs at younger age and feeling pain on the knees, it could be genetics. If not, then it is something entirely within the person’s control: overweight. I have friends who gained weight tremendously over the years even though we are only in our early 30’s. One of my friends could hardly walk for long at a pretty short distance. I reckon it is because they work from home and don’t do any exercise (some of them became too jaded and insecure over the years to go to gym), while I and my other friend work on-site so we have more physically demanding jobs and we still do exercise.

Nah bro, I’m past the big 3-0. My knees are still good (though I’ve got plenty of other aches and pains to make me feel ancient), but I’ve got friends already complaining. We’re all getting old and decrepit. Big RIP to youth 😔
