Worried Hostage

I hope I'm not too old to enjoy boating. I'm really not all that old, but I sure feel every year accumulated. My joints ache, I don't have the dexterity and agility I used to have. I know other older people enjoy boating so many I'm making too much out of it. Surely other boaters feel the same aches and pains. Surely others can't jump, climb, or crawl around like they used to. I guess we'll know soon enough. It is another of the unknowns that keeps me up at night. In a few weeks I'll probably laugh at how worried I was about all this, but for now, it holds my mind hostage.
