I'm 71 and not ready to quit anytime soon. Have a trip to Borneo and Indonesia in September. Back to Indonesia in Jan (fly into Sorong). Chile for the eclipse in June/ July (side trip to Easter Island). Probably to PNG for more diving in the fall of 2019. Trying to figure out how to fit in Sicily/Florence sometime soon. This doesn't include trips to see family, photo workshops, and more diving in Florida.
At my age (and having had ovarian cancer 10 years ago), I have no idea how long I will be healthy enough to fly or even alive, so I want to make the most of the time I have. Yes, TSA is a pain. Flying 30 hours is a pain. But diving and travel is well worth it.
