I would like to see walking sticks, but don't think that elder people should walk badly.
I know personally a lot of people who are pretty damn old and walk and act perfectly normal.
Old people that walk funny is a stereotype I would like TES to avoid.
Yes, but where do you live? If you are referring to life in a Superpower, which is unlike any kingdom that's ever been seen in the ancient world, then people do indeed walk straight even into old age, and very rarely does that stereotype get seen in those countries. But dude, I live in China, a place very much the same as it always was (although it's just now changing for the better) .... and here, almost 50% of all old people I see walk hunched over. The further from the city you go, it's more like 3 out of every 5 old people are hunched over. So it's very much in line with the stereotype, and that's a stereotype for a reason. These people lived hard lives and had to wear out their backs carrying water, and didn't have doctors or the internet to tell them how to do it properly to save their backs.
I'm sure in Skyrim, it's much the same. So I agree with the OP, because it's a reality.
Just not where you're from. Hahahaha.
