Friendly advice: China Mieville's books are EXTREMELY good but can be difficult reads due to tthe amount of poetic devices and nuance that make up his style. Also,The Scar is kinda part of a series. Events from Perdido Street Station color events from the scar, and soon with Iron Council. Finally, these books are steampunk mixed with cthullu mythos.
@jadegl: Me too, as far as coaches go. Great post, by the way, I'd forgotten about the concussion issues..that's the real tragedy in sports. These guys get about the same treatment as racehorses; racing healthy one day, glue after a trip.
@plipo: It's not mental stimulation so much as actually changing a person's brain chemistry. Exercise releases endorphins which helps to balance dopamine levels. Same with reading a good book or playing a great game. It's not emotions which are the issue with clinically depressed people, but chemistry. Our bodies...well they kinda hate us.
Now, for someone feeling down with better brain chemistry, this would be kinda a cool supplement, I think, albeit perhaps a little voyeuristic.
