As long as you have all your ducks in a row then it might be time. That situation will always be on your mind every day when you punch that time clock. A good mechanic like yourself wouldn't have much trouble finding a new place to work. Just not a dealership working flat rate unless you're good with your pen if you know what I mean. You'll know when it's time to retire just like I did. When you dread going into work then its time. I retired at 64 and never looked back. Living the dream. If you decided to retire now how long would it be before you can collect your pension? Also health benefits are a major item to consider as you aren't getting any younger and the older you get the more you need them. Meds can be very expensive if you don't have any coverage. Lots of things to consider so think long and hard.
