Exhausting the hobby = I quit counting around 40
There was a three year period where I bought anything within 200-300 miles that was less than $500.  Had about 7 at once and the oldest one left each month. EM, SS, DMD.  50s, 60s, 70s, 80s, 90s.  They just don't raise my pulse anymore and I've quit slinging them.  It was a fun 14 year ride.  
Jennifer's not completely wrong, though.  This afternoon, my wife and I are sitting on our thumbs, and she goes, "isn't there a game we can go buy?"
