Implants will be able to be bought from a vending machine in 40 yrs.

Platform Fluffy Boots, A picture of my long hair, My drivers licence, maybe my breast implants, my gypsy wedding dress.
The fluffy boots - Nobody would believe me if I didn't. In 40yrs we'll be so futuristic....no more fluffing around.
Pic of my long hair - it was beautiful but is no more, i'd put this in to show those youngens 'I was young too'.
My licence - we'll be all bar coded by then...no more i.d cards.
Implants - to remember my lovely boobs, I think they'll be a thing of the passed, in 40yrs you'll be able to buy them from a vending machine.
My wedding dress - it is beautiful, inexpensive and I'm still married 13yrs later. In 40yrs I'll still be happily married. I'd add my wedding dress to show these young ladies there is no need to waist money on a dress.
