I killed that guy on the log pretty quickly. Mostly because I met him early in the game and a lot of enemies you meet in the game are leveled to give you a tough fight. =] I have, however, suddenly been attacked by a mage called 'Challenger' who killed me swiftly. I should really invest in enchantments... I relied on them so much in Oblivion and I just always get sidetracked by other things in Skyrim. xD

I've found out that it's only possible to unlock around 80 of the 250 skill perks on any one character. I consider this a really tit game design decision, personally. I love collecting these perks and I can't remove them or anything, so I'm stuck with old decisions which - upon finding out about this - I am regretting now.
