Is this normal ?

My boyfriend has been very tired he doesn't do much but play video games almost all day. We can't work right now because of the virus he sleeps in till 10 sometimes 11 he takes a nap around 4:30 then again at 6:30 sometimes 7. He just recently started doing this. We can't get out much because of my sister's weak immune system and health problems afraid of bringing the virus to her. Is he ok ? Is this normal for someone ?
