He probably will be in bad shape. It will last for a long time, too.
Your fears are your fears. You are right to be concerned, but there is nothing you can do about it. I would steer clear from giving any advice at all, unless he asked me for it - which I'm guessing is not likely.
What is your relationship to this guy? Acquaintance? Boyfriend?
