It seems like every few years, someone comes out with a study about what percentage of the population would choose a good night’s sleep over sex. The studies are usually sponsored by a mattress company, or a pharmaceutical firm developing non-addictive (riiiiight) sleeping pills, or — as in the most recent case — a chain of hotels with extremely comfortable beds. The study, funded by Westin Hotels, found that 51% of Americans surveyed would choose sleep over sex (as we mentioned earlier this week). It sounds much less depressing if you put it the other way: 49% of us would still sacrifice sleep for a bit of raucous boot-knocking, aw yeah. But it sounds much more depressing when you learn that a decade ago, a massive 69% (heh) of those surveyed said they’d choose sex over sleep.
