Why is there Mercury in my CFL?

I just had my first bulb CFL burn out, which I am rather upset about. It's only lasted a year - although my husband leaves the bathroom light on all the time...that doesn't help. And this is an anomaly for me - I have other CFLs that are 3 years old and still going strong.

At any rate, I'm saving the receipts and boxes of the new CFLs I buy so I can return them if they don't last as long as they're supposed to. Now I have to find out where to recycle my bulb in St. Paul, which has a small amount of mercury in it. By the way, why is there mercury in a CFL? I'm glad you asked - check out this video:
"The mercury is critical to the operation of a compact fluorescent bulb. It exists in powder form, inside the glass twists of a CFL bulb. When plugged in, the electricity excites the mercury producing ultraviolet energy. Without that process there would be no glow and no light."

Humidity in bathrooms can shorten their life. Make sure your running the ventilation fan when showering and leave it on for a little bit after. I have to do that anyway, or when I open the bathroom door the smoke detector right outside the door will go off. There are some CFL's designed for extreme temp/humidity conditions.
