Wow. This speaks to me - haha! I trekked into Langtang Valley in June at the age of 63 and with two artificial hips. I carried all my photo gear and a macbook too. Thank goodness I left the banjo in Kathmandu!
Now I'm stomping around in Himachal Pradesh for a bit. Nice post!
That's wonderful and kudos to you that you did not let anything come in your way. Young or old anyone can have disabilities, but when you do not allow them to hinder you in any way, that's where you become totally free in your mind.
