I wasn't really trying to convince him, I just think making drastic life decisions based on what sounds in essence to me like "whining" is possibly less than ideal, he had many other choices available to him if simply paying a long mortgage was the prime motivating factor. I may also be showing an anti-millennial bias /sigh
I have also heard one too many stories of post-college kids doing cross-country bike rides for similar reasons and getting run over and killed, and that upsets me.
