How long does the anode rod in a 50 gallon water heater last? When do I replace it. Does it have a life span? The clorine level is at 3. Is it easy to replace?

Model # 153-332990HA, Kenmore. This model manufacturing date is 01-12-2005. It was installed in 2006. I had a plumbing co. do a safety inspection & sediment flush on 04-13-2010. Some dark water was flushed out. The anode rod was not inspected because a gas remover exhaust blower was mounted on the heater. I was not sure as to replace the anode rod since I could not see it and the installation charge for replacing it was around $225. Through your experince please let me know approximately when I should replace it? I still have mass protection until 12-2010. Thank you.
