You can be an astronaut and not go into space.

Well, can you?

I don't think, usually with NASA, when you've got two people going for the job, they don't have a fight.

What did they find in the end?

Very little.

He didn't have alien DNA or anything?

So they found... Bad news, you're not going to space.

Good news, you could do all the really annoying stuff that you'd have to do if you were in space.

Poo in this bag.

Yay!

I think they do shorten, don't they?

Twins are more likely to survive into the 60s.

According to a study by David Sherrow and James Anderson, why would that be?

They looked at the lives of Danish twins born between 1870 and 1900.

So a big old sample size.

So not so much donating going on.

Hey, stop at the start of that sentence before you get it completely wrong, because young people die through doing silly things.

But there is a thing called the twin protective effect, which basically means that if you're a twin, you're less likely to die from unexpected causes like accidents and stuff like that.

We're not sure exactly why, but it might be because you've got someone closer to you talking you out of it even maybe.

Or you don't want to be so crazy because you've got a person who relies on you a little bit.
