Will the tower stand or will the whole thing come crashing down?

For BBC Radio 4, this is Life Without with me, Alan Davis, and together we'll find out if a life without sleep is game over.

With me on this restless journey, Dirk Youngdyke, Professor of Sleep and Physiology at the University of Surrey and founder and director of the Surrey Sleep Research Centre.

And Dr Sophie Bostock, a.k.a.

the Sleep Scientist, a health psychologist who has helped everyone from Google to the Royal Marines sleep better.

I love that.

Sleep keeps us healthy, sane and moderately pleasant.

Wild animals delay sleep to migrate or escape predators.

We delay it to watch one more episode or meet a deadline.

So I've made an executive decision.

With my omniscient powers, there'll be no sleep.

Zero winks allowed, let alone 40.

It's one sleepless day in...

It's basically a worldwide all-nighter.

What are the brain scans telling us?

It does make sense, I think.

I think I'm keeping up.

That's why they stay awake for 24 hours.

They tamper with your circadian rhythms.

That's really wicked.
