I would like to commission a series of short stories from various authors.
The stories will revolve around a world much like our own, in the not-so-distant future, where medical treatments exist that cure aging. While still mortal and can be killed by accident or illness just like today, the people of this world live on average much longer - and in otherwise perfect health. They are basically in their 30s, but decades or even centuries.
Attack the idea from any angle you find interesting. What stories might this world hold that might be worth exploring?
