Bold guesses on Favre’s durability

Recently, quite a few NFL players announced retirement, and most of them are around 30 years old and none is older than 40. That’s normal in NFL, but it made me more curious about the durability of Minnesota Vikings quarterback, 41-year-old Brett Favre.

I have to guess hard why Favre could still play so well when he was 40 years old, two years after he first announced retirement. He never retired for real sense and returned to a different team every time after he announced the end of his NFL career. People got fed up with his uncertainties, but were still amazed by his excellent performance. By so far this season, Favre has not made any announcement on retirement or return, but he is highly expected to wear back his Brett Favre jersey because his performance in 2009 season has convinced people of his capability and durability. But why is he so durable while most other players end career shortly after 30th birthday or just have decreasing value even if they stay to age 40?

I have to doubt that whether the quarterback we saw on field was really the Brett Favre we talked about? Is there another man like Favre and playing as well so he and Favre can play in turn? If so, both men could have enough rest before playing his next game. I also guessed that Favre may use some kind of steroids to make his body stronger. He is 41 years old and a grandfather now, I can hardly believe he can do even better than he did while younger, and I even doubt he has a twin brother or clone to play for him when he is not in good condition. Oh, Vikings fans forgive me, I’ve just read too many conspiracy novels.
