And that survey sample is only everyone YOU know. There was an extensive thread about this a few months ago on DCUM; the OP should look it up. Many, many posters said they sleep in separate bedrooms and have beter sleep and better sex lives, too, thanks to not being next to a partner who...snores, thrashes around, comes to bed later and wakes the light-sleeper spouse who goes to bed earlier, gets up early and wakes the spouse who doesn't need to get up yet, takes up too much of the bed, "runs hot" and makes the other spouse feel overheated, and so on and so on....
Plenty of reasons to have separate beds besides medical/old/breaking up. Your imagination is quite limited. Separate beds can save marriages, too.
