what is the one thing you wish will be invinted before you die?

I need you to write some articles.  I hope an anti-ageing device is invented before I die ... actually, make that before I reach the age of 30! I love becoming more mature as a person, but I never want to have sagging skin and fragile bones. If the device could freeze the ageing process, I could live an eternity and decide when to die. It would give us longer to educate the next generation, too.
