Another reason I'm so passionate about cycling

I guess this is why my normal friends think I'm nuts.

That's funnny... You just validated their perceptions by referring to your non cycling friends as "normal" (i.e., we, in this forum are outside the norm!). I'm considered eccentric in my family, because of the cycling and running. And most of my friends think I'm nuts, too, as they make up various excuses not to work out.
