Retired scientist/engineer, age 74, excellent health, world traveler. I am adventurous, kind, thoughtful and lead a fairly spartan life. I enjoy the out of doors, biking, hiking, and until I wore my knee out, running. My usual mode of travel is by local transportation: bus, tuk tuk, bike, whatever; lodging is typically hostel or budget hotel. Trips usually last a year or more. From time to time I return to USA to visit friends and family, then leave again for wherever interests me at the time.
