I'm sure we are supposed to "age". It's natural. Obviously I want to keep myself healthy as possible, in order not to overburden my relatives or the NHS having to look after me. But "anti-aging" stuff is mainly a money making exercise.
If we all lived all our life sensibly, ate less, didn't cake on chemical products onto our faces and into our bodies, didn't inhale nasty smoke (or the chemicals in e-cigs), etc etc then we would age as we are supposed to.
I suppose a lot of people would say that was a boring way to live, but that is an individual's choice.
Stop worrying about getting older, and enjoy the age you're at.
