If you could go back in time, to witness or experience or alter any event or time period.. When? Where? How? Why?

Hmm, for me I'd say the 90's. The last era before cell phones & how big the internet is now. Also the era of my childhood & teenage years. I would alter myself and do things differently & better. I'd get myself to experience more. But I guess that's why it's the past for a reason, to hopefully learn from it & your mistakes to make you a better person & to get headed in the right direction.

Late 80's- early 90's.. I should of taken someone's advice, (sooner). Ach, we live & learn.
