Damn men and their mantabolism! lol.
I don't think he should be up all night playing games and watching TV just cuz he isn't working. He should be up by at least 9 am, cleaning the house and what not and looking for work. When I was unemployed I still go up, cleaned the house, did groceries, cooked dinner, etc. And during the day I spent most of my time looking for work, searching job sites, calling around, etc. I still went to bed at a decent hour (10-11 pm) because I didn't want to throw my body on an off schedule.
It would definitely benefit him to sleep earlier so he can get up and workout with you and start his day
