I'm not healthy, haven't been for 11 years, homebound, stuck on the couch most of the time. My kids are grown and gone, my husband works a fair bit of overtime, and games keep me occupied. Through them and my avatars, I walk through the woods, swim, garden, shop, socialize, save the world. What game I play at a given time depends on how I feel a particular day; it's not good to join a dungeon group in WoW when brainfog makes it hard to remember which class I'm playing, much less how to play it, and Sims 2 is tedious when my brain is clear. Sims 2 is the only non RPG game I play, btw.
So, usually it's 6-8 hours daily, but can easily top 12. A weeks' gaming = 50 hours at least.
