So http://www.youtube.com/watch?v=imH4Ncoe9Gs&feature=player_detailpage#t=335s you can see that man Hod pretty much lift that giant log by himself, which should be pretty heavy and it should be a troll lifting that log not a man.. in fact people at quakcon went 'ooooooooooooooooooooooooooh' when they saw him lift that log. Do you think that jobs would require some sort of skill level requirement? I was going to say strength, but then I remembered it isn't in Skyrim.. so maybe stamina or hand to hand requirement? Discuss.

Going back to most TES games likely not. It would add something to the game if this was the case though, kinda like how you have to have a certain skill level for trainers.

You probably won't be lifting logs like NPC do. And Hand to Hand isn't a skill in Skyrim.

I assume that guy has a powerful artifact to enhance strenght, maybe part of a quest

Patience for grinding all these wood is enough.

i think mite require smithing skill level is to use the saw mills to fuel the furnace !
