Absolutely I would. I'd go back 25 years and change a lot of things regarding how I raised my Son. Knowing what I know now, I'd do many things differently.
I'd also not get on my motorcycle on August 20, 2006 and avoid the wreck I had.
The further I'd go back, the less medical knowledge there would be and less rights I would have (gay rights and just human rights in general) so I think I'd rather just stay in 2013 haha
