Some people don't handle retirement all that well. I retired in my early fifties and never looked back. I live in an area where I can be out hunting or shooting in five minutes or less. Fishing isn't to bad either. Spend alot of time afield, especially during upland bird season. Also spend alot of time shooting prairiedogs and shooting in general. Do a lot of load development for people. It's really great to shoot other peoples guns, especially when its there ammo. Spend alot a time as training instructor for our local volunteer fire dept, and belong to an awesome bowling team. Do alot of cooking, grilling, sausage making etc. Have alot of parties out on the deck. Wife and I do travel quite abit to Idaho and Montana to vist friends and the kids. Fishing can take up alot of time also if you let it. Spent this beautiful day out in the Badlands on my skiis with my rifle strapped to my back and some coyote calls in hand. Had my Lab along for company. What a great day.
Have fun thinking about your retirement. It can be alot of fun if you are ready for it.
