Hi! I'm 57 and my job involves shift work. I am working 12 hour shifts. Usually it's two days together, and then every second weekend it's three 12 hour days together. The two 12 hour days together are not too bad, but the 3 x 12 hour days leave me feeling I've been run over by a train. It seems only in the last 2 years that this has become particularly noticeable. Just wondered if anyone else is working shifts in their 50s and experiencing the same. I also have arthritis, so after 3 long days, I am in some pain. I don't think I can do another 9 years of this until 66. Would welcome others experiences or ideas re same.
