I too took early retirement (age 58) from a large communication company. What made it possible was the health insurance that the company continued to pay till Medacare kicked in, and now supplies a low rate supplement. Without the health care thingy, I would not have retired at the early age. Also... Retirement is NOT over rated. The wife and I are busier now than when retired, and have to sometimes say the word NO to some peoples activities. As Christians, we do enjoy medical Missions trips to countries bringing the Gospel to many and other volunteer activities.
So after saying all this, our other passion is camping mostly dry camping from 1 feb to 1 may in Ariz/NM. Summer is spent camping in many short trips throughout the area and to our family camp.
