Happy B'day Muckabout. (FWIW, I'm exactly 10 yrs + 1 week younger). As we've gotten older, we switched to roller furling headsail & electric windlass. That's been the only change in the hardware dept acknowledging our diminishing strength. We reef earlier and sail flatter - in general a bit more cautious. We sail just about as *often* tho we plan shorter days when practical. Back injury makes me unable to walk as much as I used to, but since age has also made a little alcohol go a MUCH longer way, the money saved affords car rental in other cities LOL.
My *brain* doesn't feel any older, just my body - and the sea is just as beautiful.
