[Semi fluff] Age, is it just a number or does it dictate how you are supposed to act and dress?

While hacking around the Net, shopping, investigating, checking email, etc. I followed a link off one site to another and some fashion police was saying what not to wear after a certain age. The part I viewed was mostly women fashion, there might have been fashion ”don’t” rules for men (I can think of a few that might have been there), but I found it so hypocritical and ludicrous I abandoned the article before I got half the way through it. But it made me think, some say age is just a number, others say you are as young as you feel, other going further say if you have the physique for anything you can wear anything at any age, then you have this article which suggest even if you spend time in the gym or doing other activity that keeps you trim and fit, simply because you get on the wrong side of 30, 40, or even 50 you should not wear but avoid certain items or fashion trends simply because you are too old and dignified to degrade yourself wearing garments best left to younger people 30 and under, etc. Where do you fall, age is just a number, you are old if you feel old and young if you feel young, if you want to bungee jump at 56 years of age and not throw a hip, go do it, skydive at 70, OK, or once you hit a certain age, put away the muscle shirts, don’t dare wear those Speedos, forget about those 5 in pumps and any hemline above the knee, etc.?
