Thanks Penny, I think we had this chat in Quora. I’m 41 and in good health. I’m still very mobile and can go for a good long walk. I do have osteoarthritis in my knees. No, the weight won’t be helping but it is a family curse. My mum and grandma have had both knees replaced but my two very slim and fit aunts need theirs done too. My standard size sister has it in both her knees and hips.

im not saying weight can’t be a problem as you get older but I would say it’s not a given. It depends on how much you exercise up to that point.
