To experience life in the upper class of the second to last generation of humanity, Generation Y. It's a learning experience and my post-human soul will have this life added to its knowledge along with all of the other lives it has lived.
I was given a choice of this one or coming back as a cockroach. I chose this one. However, had I taken a closer look at life with my ex-wife, I might have chosen the cockroach.
My life's pretty cushy. I want to know how sucky your options are to choose dieing young in some horrible way. I think if it is a genuine Buddhist belief its purpose is to make you more engaged with reality by accepting it as yours. Probably more worth dwelling on that.
Why do you think you picked this life?
