I agree but I think there is an evolutionary reason why we need sleep. Some animals like sloths for example need for more sleep than we do, others need less. I guess it allows us to cognitively function to our optimum capacity. It is evolutionary though so I guess if we wanted to train our minds to accept 30 minutes of sleep then we probably could.
Indeed acutally 8 hours sleep is generally regarded as too much. The problem is that humans really should sleep for a couple of hours in the afternoon at around 2-3pm. You may notice that you are pyschologically dulled at this point and this because the brain works on a twenty-four hour cycle. But of course modern living etc doesn't permit you to have a nap in the middle of the day (unless you work for one of those big corporate firms of course where you have your own hammock under your desk).
