yep time seems to slow down but actually its your perception of things and the information yo can take that goes sky high. Also, you can get faster or more productive since your concentration is maxed out, for example, when I do the dishes on a high well Ido it quicker and better and without additional efforts but if do it with no high well its a real pain in the ass for a start and doin it as fast as I'm high is possible of course but again such a pain.
