Random Thought: Time Travelling

Last night I was having some trouble sleeping and I started to think about time travelling. I was thinking that if it were possible in the future and if it were easily accessible (like it is in the movies), then how come I haven't met my future self yet?

I came up with a few reasons:

• My future self chose to meet me when I was too young to recognize or comprehend who he was.
• My future self was too old to recognize.
• The intergalactic robotic war in the future had left my future self so disfigured, I was rendered unrecognizable to my current self.
• My future self used a memory clearing device on my current self thus removing the event from my memories (like in Men In Black).
• My future self dies before the technology is widely available to the public.
• The Space/Time Lords of the future demand that all time travellers wear either a cloaking device or a temporary full body transformation device when travelling to the past.

I know, I'm a geek who has watched one too many movies. But it begs the question, if it were possible to meet a version of yourself 30 years from now, what would you ask him/her? Or what do you think your future self would like to tell your current self?
