Alzheimers?

When is the age of onset? Can it start in your 20s. Maybe my ass is just forgetful as all get out. It took me 2 weeks to remember to buy some AAA batteries. I just bought some AA's after a 3 month stint without them. I have been meaning to buy this composition book all damn semester. I often go to the store reciting what I;m going to buy and then I get in the bitch and I look stupid. I don't remember why I came here. I try to make lists but I cant remember to save my life to do that either. This is why folks live with the 'rents so damn long. They wouldn't have you toilet paper less or without juice. And why can't I get me a damn lunchbox so I'm not starving up at school all day. Oh I know because I forget.
