What would you do with a second life?

Signing a copy of Irina: The Trilogy  for Caitlyn..

Yesterday, a student read a story in which he'd found a magic stone that granted him a 'second life.' This concept -- astonishing from a grade four pupil -- seemed to me a fascinating premise for a piece of speculative fiction. Assuming you keep your current life, and all the precious experiences within it, what would you do with a second life? Would you pretty much have the same life, with just a few things revised? (Saying yes to a job offer, exploring unused talents, doing things you wish you had time for,  actually making those fabulous comebacks we think up later...) 
           Would you run your 'second life' at the same time -- so that you could be a greens activist, or a pilot, or a spy -- and have adventures, and then return to your 'real' life? 
            And if there were no constraints, and you could live in another country, in another time, in another body, what would you choose?

Thanks again to the Grade Four class at Croydon Primary, it was wonderful to visit, talk with you about reading and writing, and hear your stories.
