Left real day job after 35 years and now am semi-retired - I'm 56.

Pluses:

It's nice to not have to be at work at 8 am and take orders from a boss. Still spend about 8 months out of the year owning/operating a seasonal business. Don't have to worry about setting the alarm clock unless you have something special to do. You feel like you're a teenager (not your body) with all kinds of extra time on your hands. You actually start "living" again. Travel more. Run errands when everyone is working - no crowds - and eat at nice restaurants for lunch thus saving money. Take advantage of senior discounts.

More time to look for games and find games. You can drive right over there to get a game and not have to wait anymore to get off work. More time to work on your own games and games you want to sell. My collection is constant at 13 but I usually have anywhere from 15 - 22 pins around. There's been more since I retired.

Minuses:

You're getting old as dirt. You're body just doesn't work like it used to. Aches and pains increase with age. I still move em's by myself all the time so for right now I can still stay in the hobby. I'm hoping to stay in it until 70 anyway but we'll see.
