Bed sharing 'drains men's brains'
From BBC News
Bed sharing disturbed sleep quality.
Sharing a bed with someone could temporarily reduce your brain power - at least if you are a man - Austrian scientists suggest.

Is the claim true for gay men since the study sample only included hetero couples?
Am I getting dumber? Is my BF getting dumber?
Is that why I find Professor Layton's puzzles harder now more than ever?
Maybe they had it right in the old movies and TV shows when couples slept in separate beds.
However, I don't doubt this statement from the article:

"Bed sharing also affected dream recall. Women remembered more after sleeping alone and men recalled best after sex."
