This week I discovered a cool article about people who can't feel pain. These scientists discovered those with a rare genetic condition prohibiting them to feel pain also lack the ability to smell. They believe it is because we use the same signaling channel in our brain to feel pain and sense smells. This channel is active in the olfactory system, which is connected to smell. Now these researchers are worried that drugs diagnosed for pain that hit this channel could possibly wipe out the patient's sense of smell. I think it is really mind blowing that two seemingly unconnected things could be so interrelated in your body. Also, I will be asking lots of questions before ever receiving pain medication!
