I have no problem with my age. And I am not close to being old. I have no problem doing anything that a younger person can. I play basketball with my team at work 3 times a week and everyone playing is half my age. I am proud of my age. You are using it as an insult. Which is sad.
this is exactly why you are insufferable. you say you have no problem with your age, and then you go on to warrant how superior of a human-being you are! it's insulting to the rest of us. you can say you can do anything a younger person can do, but the truth is, those kids run circles around you on the court, they don't wake up with a sore back, and then they go out drinking and partying while you're in bed by 9pm.
but you can be whoever you want to be on the internet, so keep being the 48 year old super athlete who has the best musical tastes, the best looks, the best taste in beer, the best education, and the definitive voice of reason.
