So people are doing this for a thrill? Why not take up mountian biking? I guess riding on the road is boring after awhile, I just havent done enough road miles yet. (this is my first road bike, I had one 10 years ago but prolly put 50 miles on it)

5 year olds dont have the 25+ years of riding muscle memory I do either. Unlearning something can often be more difficult than learning something.
