I actually found this stuff really interesting.
I know this is self-selecting and probably BS, but I'll say it anyway: As a group, I've found serious cyclists of older age to be of higher intellectual caliber than the average person. Maybe it's a statistical anomaly ... I dunno.
What I'm reading here kinda confirms it. And as noted, it's not all noodle salad. Sometimes, having a high IQ isn't what it's cracked up to be.
If I were someone looking to do a PhD thesis, I'd have found my topic.
