Yes, travel has a way of doing that to you.
This superb little travel video describes a journey across China by Christoph Rehage in 2008 and demonstrates quite well that it's still possible to make your own extraordinary adventures these days.
This wasn't possible in the days when I explored China, but even if it had been I'm quite sure I wouldn't have had the patience, yet it captures the changes in the man created by the journey.
Wonderful editing.
