Er, yes you do. People have tried not sleeping for 10 days or so. It's not pretty. (The important bit is the REM, it seems.)The same goes with getting older...there is no genetic proof that we need to age at all...its all fucking wierd and I want to know more. enlighten me.
Well, the basic problem is that cells can't replicate indefinitely--they slowly accumulate errors, etc. Something about telomeres goes here. I really don't know my biology.
Even if you gave all your cells telomerase so they would never shut off, they'd still accumulate those errors. We're cancer waiting to happen, really.
