Neil Kendall-Cheese asked the Naked Scientists:
Hi Chris,
I often listen to your broadcasts (http://www.thenakedscientists.com/HTML/podcasts/) and enjoy them greatly.
I have been sitting here,in bed, working on my laptop. My wife is next to me and she rolls from side to side. That made me start wondering, why don't we fall out of bed very often, if at all?
Probably a silly question, but nevertheless one that puzzles me.
Keep the broadcasts going.
Thanks,
Neil.
What do you think?

Possibly because we are partially or totally awake when we roll over in bed ...

The bed graphs show the typical sleep patterns through a night for an 18-year-old and a 75-year-old, with the pie charts showing totals for the different stages of sleep. They illustrate that as you get older you spend less time in deep (delta) sleep and more time awake.

Could there be also a link to the familiarity of the bed and its location?
When the current Mrs first moved in with yours truly, she fell out of be quite a lot. Or did I push her???

An 18-year-old who only spends 8 hours in bed? There's a novelty!
