Like my grandma always used to say "age is nothing but a number" in fact she used to ride this old bike she probably bought in the 50's, fixed gear, she didn't have brakes on it, and she rode it until she was 65.

Anyways I am 38 years old and brake-less for life just on a fixed gear, no need for brakes on a fixed. My road bikes and mtb's of course have a brake or two.

Cheers!!
