In reply to Mr Moac:
I would say not. I grew up with a dad who played rugby quite well. That involved him training two or three nights a week, and matches all day on Saturdays. Then there was coaching the youth teams on a Sunday. I don't begrudge him that at all, just telling it as it is.
I have also lived with a very good runner, who trained everyday and would race frequently too. I think that anything less than dabbling in a sport requires a significant time investment. So, in answer to your original question I do not think that climbing is more selfish than other sports.
