One dad DH and I were out riding our mountain bike on some woods roads. A little old gentleman drove by and waved. Then a few minutes later he came back and stopped to ask if we were lost. DH told him no, he knew where we were, he hunted all over the area all his life. We chatted a while and the gentleman asked how old we were. I told him I'm 55. He said he thought perhaps we were in our 80's like he is. Now that will burst your bubble.
