Extra memory required

If only humans are able to upgrade their brain memory capacity like how we used to upgrade our computer memory, I'll do it right away! I've been so forgetful lately and I've been sticking 3M post-it notes everywhere to remind myself of my daily chores. Not only that, I've been misplacing things around the house too. For example, last week I was supposed to take the oyster sauce out of the fridge but as I open the fridge door, my mind went blank and I don't even remember why I open the fridge door in the very first place! Scary isn't it? I believe all these happen partly because there were too much things running in my mind. I need a break! Argh!
