Not if you knew how little he worked when he is at work.... Remember I know this man very well (I am his best man after all) I can assure you he is lazy - not exhausted
In addition to this some of our work hard and have kids too you know (myself included) - and IMO the hobbies are needed to keep the sanity and health levels up.
Glad you know him better than I do though!

For an update i have worn down his complete rejection of activities - so just need to pick something that i think he will enjoy that isn't paint balling and go karting.
He has been to Go APE before and didn't enjoy it.
He hates water sports (so rafting etc is out of the question)
Thanks for the suggestions so far though! If you think of anything else keep them coming.
