I don't know about that, but I know bitterly that chronic sleep deprivation basically deatroyed the "RAM" of my brain, now it's really difficult to concentrate and go through difficult problem without rest. So instead of gritting through step 1 to 10, I have to take a rest after step 3, then make sure that step 3 was property done, then take another rest after step 6, recheck 6, and so on. I'd argue one of the edges smart people have is to have a large RAM. They can think through all 10 steps in one shot, maybe 20-30 mins, while people like me have to take triple that time, even a full day because something interrupts us in the middle. Conclusion: don't f**ing get kid(s) unless you really want them, as air and water, and are willing to sacrifice cognitive ability.
