This week's video comes from Mur Lafferty over at I Should Be Writing. While at first it may seem pessimistic, watch the whole thing.
This isn't the first video in this vein: the AARP had a similar ad, and I'm led to believe that the original was an Argentine advert that won an award at the Cannes Film Festival.
Whatever its origins, I'm impressed with it. I hope you enjoy it.
