I’d be slightly wary of too much running, especially if you’re doing it on pavements and roads. I was a regular cross country runner throughout my 40s and early 50s (8-10km, 3-4 x pw) and I really loved it, but now, at 59, one of my knees is pretty buggered.
I still run a bit, but only on a treadmill and never more than 5k. I know lots of women continue to run happily into their 60s and beyond, but if running is your thing I’d start to take good quality joint supplements as a priority - glucosamine, condroitin, cod liver oil and creatine to help build muscle.
As a pp said, your face is going to do what it will according to your genetics and sun exposure, and no amount of expensive unguent will change that, although I do think daily facial and lymphatic massage helps a bit.
From a vantage point of 20 years your senior, I’d say that the most important thing is to do everything possible to maintain your mobility, flexibility and strength, but don’t be reckless with it. Weights, Pilates, walking, good diet. You don’t realise how vulnerable/miserable it makes you feel to be incapacitated or in chronic pain until it happens to you, and it’s the quickest destroyer of your confidence and quality of life.
I’m a lot less gung ho now in my approach to physical fitness because I know I’m not invincible, that it’s not necessarily a good thing to ‘push on through’ when your body wants to stop, or you can’t quite get into that yoga position, and that - as with most things in life - moderation and mindfulness serves you better than overdoing it.
