We are traveling with friends which we did two years ago. In that interim time, the husband of the pair had a heart attack and triple bypass surgery. While he is in remarkable health now having made dramatic life style changes, there are some nasty side effects of drugs he's on. We did a lot of easy hiking today to see the amazing Giant's Causeway and it was a tough but worthwhile hike for him. It made me appreciate the good health i'm in now even more. It lets me do and see things that so many people cannot if they do not take care of themselves.
