I hope in my life time I invent the hover wheelchair solely just to say "Whaa I just don't want to do **** when I'm older" while accepting an award for it.
I just discovered that there is an alarm clock that makes tea for you when you wake up. It was popular in Britain for a while until it wasn't for some reason. On one hand it seems almost comical, but if someone gave me one as a gift I would totally use it.
