A couple of Nepali kids play tag on a suspension bridge... I walked the Annapurna Circuit in 2011 over 25 days. It was supercool, and I felt healthy and happy and great, and met all sorts of friendly people, old and young. It was tough at times, and got me thinking about youth, and that old Twilight Zone episode called 'Kick the Can'. It's about how you are only as old as you act, and is a classic. At the end of the episode, Rod Serling says something about the fragile magic of youth, and how it is intertwined with maturity and old age, not separate.
Kick the can or play some tag. Suspend the inevitable as long as you can.
