Let him talk about the weather, hockey, football, talk about basketball, baseball....whatever you discover that he enjoys talking about.

My wife is 36, I play basketball 2-4 times a week with the 20 somethings as well as workout most days and feel it in the evening. 

My HOA pays for a pool, gym, basketball courts, water, sewer, trash, and security.

Gave them a basketball goal left by previous tenants 

Several years ago I coached a girls AAU basketball team.

I was averaging 100 miles a day driving I think when this hit, driving to work and back, then to a soccer/basketball practice and back, getting home late almost every night. 

This obviously doesn't help the person quitting cold turkey, but can be very useful for those trying to quit "the habit" of smoking.I never smoked more than a few a day, but getting rid of the routine (i.e. not smoking in my car) followed by cold turkey after I had quit smoking in certain situations worked for me.By the way, I'm twice the basketball player I used to be since I can now breathe the way I'm supposed to again!

He's an investor himself and knows the game. 

I played a lot of basketball, so ‘stretch’ and ‘big man’ showed up at the beginning.

A baller is one who plays ball (basketball, baseball etc) and is very good at it.
