I had bought an ego-C last month. Quite enjoy it and it's helping me quit smoking. Recommended it to a a guy. He came up to me today and thanked me for recommending it saying he's been breathing better and he's quitting now too. It was nice. Also had a discussion with a guy about the reasons I don't personally stand for the Pledge of Allegiance (No, I don't. No I will not argue the point with you.)and he turned out to be a veteran. He said my views on it were quite legitimate and he was okay with it. Thanked him for his service and didn't have an argument. So all around interesting day.
