Unintentional or intentional. Whatever amount of time you personally consider to be nap-length. I'm really curious as to what others' patterns are in terms of napping. Also I'd be curious about your age if you don't mind sharing it. I know some who live by/for naps and others who oddly despise naps. I enjoy a good nap myself though I suppose I wonder if I take too many and would be better suited to try and get more sleep during real sleep time so to avoid taking them as often. So, do you like to nap often?
