I guess it depends, I used to travel a lot when I was in my 20s (I guess it would add to about 5 years spread over 8 years period) and now after close to 10 years being home it just feel like it never happened: sure I do have some memories, stories and some connections on Facebook to people I haven't seen in many years. Don't get me wrong it was fun and interesting, but I guess thats it.
But maybe thats me, when I was traveling I was feeling happy and excited, but I feel same just walking in the park outside my home and actually looking forward to just get my coffee at usual place and spend time programming. Basically same routine, now I just have more comfortable setup.
