You would knock up your own grandmother? That seems a bit... sick. Not to mention that your genetic makeup would change completely and you'd probably become an inbred.
I've made to many mistakes myself to change anything to really help me if could only change one thing. I would go back in time an prevent something very bad from happening, maybe when I come back to the present the world would be better...or we could be more technologically advanced
When I have a grandchild (me) I would tell him his future like "You will knock up your grandmother"
You would be inbred, and then if your grandson goes back in time and does what you did, he'll be even more inbred. All you'll accomplish from doing this is creating a never-ending loop of the same person becoming more and more inbred.
I would have chosen to live with my dad when my parents divorced when I was seven. That way I wouldnt have had to deal with the crap I've had to deal with for the past 8 years.
