I got the swine in 2009, and I don't remember ever having the flu so bad before. I haven't gotten the flu this year either, but I don't generally get the flu on an annual basis, so that isn't too surprising. If he though that the H1N1 was more mild than any other flu, then he either got the anti-viral really early, he is old enough to have some immunity as teenagers and 20-something apparently react the worst to H1N1. Neither of my parents were hit quite as hard as my brother and I, but they were still miserable, or he is blowing smoke out of his ass.
Mind you, mine turned into Pneumonia as well, so my experience was anything but positive.
