48. I've been cycling for about 24 years. At first for transportation in my early 20's. Then, I lived in a hilltown on dirt roads so I used a mt. bike every where I went in my late 20's to mid 30's. Then I moved where there were more paved roads than dirt, and bought and started road biking as that made more sense. I've always been athletic and outdoors oriented so this has been a lifestyle my entire life.
