As in, why can I balance my bike fine when I'm going fast enough to keep up with traffic, yet not if I'm still? And why do I have to rest a paddle on the water to stop me capsizing when I'm not moving in my kayak?
Do standard anticlockwise running tracks favour right-handed
runners? Do right-handers win disproportionately more track events than
left-handers? If not, why?
One criticism levelled at soccer is that the game can be unexciting
as not many goals are scored in most matches. What would be the
likelihood of goals if the rules were changed to allow two footballs to
be in play at the same time?
Why are four-person bobsleighs faster than two-person bobsleighs? Is it because they have two extra
people pushing at the start and therefore are faster throughout their
run or is it to do with weight and momentum? Surely there comes a point
when the extra weight slows the bob too much? A few friends and I spent
an hour or so arguing over this the other week, divided into those who
thought it was the extra weight and others who thought it was the extra
runners.

I have heard on numerous occaisions that it is dangerous to press a weight from behind the head, or pull a resisted bar (e.g. lat pulldown, pullups) behind the head. I have heard a few theories, based on either rotator cuff limitations or the risk of damage to the cervical spine. Anybody know of definite evidence/proof or even with solid reasoning and not just naming a few anatomical structures? Thanks
