13.5 Hours running a dollar store and 13 hours on a mail route.
Additionally I once spent hour upon hour (I'm not sure how many) watching the first 3 Tremors movies as a marathon.. Actually I've done that more than once.
I'm sure I've spent many consecutive hours on the computer/internet... Sadly.
My GaiaOnline account would probably show that I've logged many hours. Especially durring their Halloween holiday games. (I haven't done that in 2 years though)
