I'm leaning towards no, since I haven't had more than a very mild cold/flu in nearly 5 years now.
It's amazing how much weight alone can apparently affect your susceptibility to colds/flu. When I was a 320 -350 lb land whale I got a bad flu every-single-year. Like, spewing from every orifice bad. Once I got down to 180/190, and started working out and exercising, well, haven't been more than very mildly sick since, and even that's uncommon.
Sooo, I voted undecided, since I'll occasionally get it if asked, but leaning towards a flat no anymore, since it just doesn't seem necessary for me now.
