Sleep is a double-edged sword.

Sleep is pretty awesome, it helps rest your mind and helps improve memory and all that good stuff.

But sadly sleep has its negatives, the main one being it takes away a lot of free time.
Or it can make you not want to wake-up, and you'll be late for work or school (happens to me every day xD)
Another problem is if you want to do something, but can't because you're too tired and need to sleep. Or if you just can't think straight because of lack of sleep.

So I've often pondered if life would be better without sleep.
The main problem that arises with this is that, if people didn't sleep, then work and school would most-likely be a lot longer. And that doesn't sound like a good thing xD

A compromise would be if the world rotated slower, and a day would be something like 27 hours instead of 24 hours.
This would allow for 3 more hours of sleep a day, and most people with busy lives would probably benefit from this.

Of course that also has negatives as well. For instance, if you're waiting for a certain day to happen, you'll have to wait longer. In fancy math terms the extra time you'd have to wait is (3 * n) hours longer where n is the number of days.

Furthermore, if you're having a bad day, and want the day to end, you'll have to endure that bad day for another 3 hours =D.


So really, I'm not sure what could be done to solve the problems of sleep. All options seem to have their ups and downs.... but that seems to be the case with most things in 'life'.
