Best wishes to your wife for a speedy recovery, Winton. If it's any comfort, I had a heart attack in late November 2009 and needed a bypass in January, 2010. Since recovering I'm healthier than I ever was. I stopped drinking and sorted my diet so that I've dropped about 20 pounds (1.5 stones to me). I've played rugby and I'm planning to do a 24 hour, 66 mile hike in 2015. Modern medicine being the wonder that it is, changes in lifestyle (ex. my pipes, obviously!) and the right medicine means that I'm set for years yet. Look after one another and take it as a wake-up call for you both and you'll be all good. Oh, and I plan to go over the finish line with a pipe in my gob!
