I don't know, I think that if I had to choose between going to the past or the future I'd prefer the past. It just scares me a little bit thinking about the future in terms of our planet and I'd be totally devastated if I see nature disappearing. Every time people talk about the future they tend to focus on technology and seems something interesting but in y case I'm not too keen on it.
If I  could go back to the past I'd like to warn somehow about events that have affected people, like in earthquakes, evacuations, etc. but I think I wouldn't change anything about my own life; of course I've gone through bad things but I don't know, I'm fine with that. 
If I had a travel machine I'd love to travel and see dinosaurs, of course the vegetarian ones otherwise I'd die immediately. So I'd be there for a couple of hours just contemplating these wonderful animals and the landscapes of the prehistory.
