Sorry to hear about the ailing loved ones, it's tough, and like Fob said, I think we're getting near that age where it seems like everyone is going through it. I am lucky for now, my parents are younger (my dad turned 60 last week) and in good health; but my grandmother, who I've always been close with, has been in bad shape for the last 6 months. Scary part is she went from being in perfect health in January, to having some dental surgery in February, then falling on ice a few weeks later and breaking her leg, then just has she was recovering from that she ran into some intestinal issues. The 3 surgeries have not been easy on her, an at 84 she's gone from being full of life to having almost no will to live in a matter of months.
Oh, and I am often guilty of driving around with the top-up on nice days.....The sun beating down on you gets old really quick, especially if you're in city traffic. Nighttime is the best for top down driving.....No sun, and less noise/confusion means you can really get to enjoy the openness.
