Imagine if our bodies didn't need to sleep. We still need to eat and drink to survive, but we don't need to spend 8 hours a day doing nothing.<br><br>What would our daily lives look like?

Would we be bored out of our minds after a while?<br><br>What other things would change? Schools? Work schedules? Health? Leisure time?<br><br>What do you think?
