Things I wish had been invented

Really! There are some people in the world that I wish would not come into my little world. A particular person that I have to interview today, for example. But rather than vent here about all the little things that are ticking me off (which will go on forever and bore everyone including myself), I have come up with a list of things I wish had been invented:

1. Mute buttons for people who spout crap incessantly
2. Long-lasting anti-idiot spray that can either temporarily turn people into non-idiots, or just clear the room of all twits
3. Internal watch-synchronisers installed at birth, so that when you say you're meeting someone at 12, they don't turn up at 12.27
4. Instant-friendliness chocolates, to feed to certain rude PAs and their even ruder CEO bosses
5. Bitch-alert radar
6. Invisible capes
7. Teleportation devices
8. Anti-taxi forcefields for cars
9. Compulsory training in manners for all business people
10. And, of course, free therapy for all members of the media!

So tell me, what do YOU wish had been invented?
