Usually this happens... people who are not willing to fight longer and harder are just prone to choose something obeying like religious thing, running far away in some isolated village and so on. If this is what makes him really okay, let it be. The danger is he's still young and if now he ruins his health, his chances of the youth and his abilities, when he is middle aged (like us) or old (like some of the users here), he will see it is too late probably... I hope for the best for him just because he's such a great person: educated, well mannered, suffered before enough, with good intentions. I like him.
