So I've had this problem for a while now and I'm not looking for medical advice or anything...just your thoughts.

I have never had a broken nose or anything, but my sense of smell is very weak.  I can smell some things.  Food usually come through with no problem.  At least, I think it does.  I can smell gasoline at the stations.  Perfumes, colognes, or deodorants I can smell.  I can smell crap.

However, a lot of other things don't.  Take farts for example.  If someone dropped a room-clearing bomb nearby, I wouldn't smell it, which is odd since I can smell crap.  When my sister moved into her new house, there was a slight gas leak.  Everybody else smelled it clearly, but I just had a faint sense of gas.  I would have overlooked it if I were alone.  A certain plant near her home gives off a horrible odor when you drive by it, but I never smell it.

Obviously, this is something I need to see a doctor about because smell can be important.  Yet, part of me enjoys laughing at others gag from a fart while I just sit there and breathe normally.

What do you guys think about it?  Have you ever heard of something like this?  Is this a blessing or a curse?
