would switching to a polyphasic style of sleep be healthy? most doctors say you need a good 7-8 hours sleep a night (as an adult). but would someone miss out on the "rest and repair" which sleep brings by having a polyphasic sleep cycle?

'Dangerous' Exercises

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

Why is sneezing such a pleasant sensation when most other expulsions (i.e. coughing and vomiting) are not?

Tailbone trouble? I was studying anatomy in school but as a class we just could not get around the uselessness of the tailbone. Did we lose a tail? Is there a similar structure in other animals? Are there any other useless parts of the body?
