You have GOT to be joking ... right? That sounds exceedingly mundane.
No joke.
In fact, one of the mods I made allows me to use Firewood in various crafting recipes (in vanilla all it's useful for is improving Long Bows and selling for early cash), and on my current character I've probably spent at least 6 of his 25ish hours chopping wood. I also spend inordinate amounts of time at the Alchemy tables seeing how many different effects I can get in one potion, as well as out gathering/purchasing reagents.
My first two characters, both retired, have over 150 hours each; that includes using Fast Travel all the time, but also includes detailed exploration of each dungeon and of the area between my current location and the current quest destination. As they were made for exploratory purposes I didn't care if they found everything or not, since I was using them to collect information for my more serious characters; those will each have well over 200 hours, despite RP-based limitations on which quest lines they will do, since I will be taking my time with them.
I'll still be using Fast Travel, though, since it doesn't actually get in the way of exploration. After all, you have to find a place before you can Fast Travel to it, so if I'm 'zapping' myself to a given location that means I've already been there and won't miss anything by not pacing it off instead. On the other hand, I'll also be spending a fair amount of time trying to scale cliff-sides I'm not meant to, as there are a fair number of small stashes hidden away in obscure cracks in the rocks that you'll never find if you stick to the paths. Not that there's anything great in said stashes; the whole point is to actually find them, then chuckle at the joke that particular developer was playing on someone when he or she hid the stuff there. As a side bonus there are some well-hidden Ore Veins up there too, so I get some crafting materials in the process.
