Sterotypes

My friends over at KnittingHelp.com were talking about sterotypes today. What do you think of when you think of a knitter? An old lady? I've been told that I'm young for someone who knits. Why is that? There's no age limit! It's a really fun hobby and who cares about your age or gender or whatever. I understand that humans like to categorize things, but sterotypes just aren't that helpful. So many people don't fit in them, that they loose their usefulness as a category. There are people of all ages in my local knitting group and groups I've been in elsewhere.
