My dad is in his early 70's and lives in another state. I don't see him more than once or twice a year, but I just went and visited for a week.
It's tough to see age slowing him down. He mentioned that he recently went to change the oil in my mom's car. He has a pair of logs that he cut with a chainsaw into car ramps. When he pulled them out to use they had gotten too rotten to be 'safe' so instead of cutting new ones or buying actual ramps, he decided that his oil changing days are over, drove to town and paid some guy to do it for him. It's the end of an era, chokes me up a little.
