If we have "always" been getting "not enough" sleep, then for sufficiently large definitions of "always" I begin to question the "not enough".

The twentieth century saw a lot of poorly-informed scientists second-guessing human body mechanims that have been keeping us alive for millions upon millions of years, on the basis of "studies" that constituted tiny, tiny, tiny, tiny samplings of a horrifically n-dimensional parameter space. I don't think the twentieth century scientists came out of it looking too good even now in 2015 and I expect them to continue to look worse as we learn more. This seems as likely a place as any for them to end up having been wrong.

enough probably means optimal not baseline to function adequately
