Separate Beds VS Same Bed

A survey from the National Sleep Foundation found that almost one in four married couples sleep in separate beds.
 
I know snoring can really be an issue.  I've fortunately found great ear plugs that I buy online from Canada that help a lot.  Having the separate covers also helps, so if I pull gently on my husband's covers, it disturbs him just enough to stop making so much noise!  So sleeping in the same bed actually helps us in this situation.

I am surprised about this statistic that so many couples choose separate beds. Are you?
