Im 26 and use quad skates for roller derby. If its something that you like then do it :)
Nobody is ever too old for rollerblading. It's a common form of recreational excercise. That's like saying you're too old to ride a bike or go swimming.
Your body will tell you when you're too old. When you finally can't do something then you'll know. If you are 80 yrs old and still rollerblading, you will probably be an inspiration to others.
no cant ever be too old for rollerblading or ice skating
Of course you aren't too old. Don't forget the helmet and elbow/knee pads though. Or it will end in tears.
