I wasn't aiming to go that deep, but to answer your question I meant the ability to perform any given set of tasks. Deriving the second conclusion needs a lot more data. Assuming there is no analog for swapping to disk, the biggest missing piece is the rate of GC. Is it the same for everyone? Additionally, is a given person's GC rate constant? When I go without sleep for two days, I usually need more sleep than when I missed sleeping for just a day. Does this mean there is more memory to reclaim? Or that my GC rate has been impaired? Or both? More interestingly, how do 'brain-building' foods and activities affect sleep requirements?
