If you work around sick people a lot

It will eventually catch up to you. I had to be relieved early last night, and I am off work today because of a stomach virus. Clients and staff at my workplace have been sick, some of them numerous times, since before Christmas. I leave it to your imagination, but it involves losing it at both ends, and stomach cramps and headaches and body aches. I usually am immune to this, and in fact, I think the last time I threw up before last night was about eight years ago. I feel whiny and miserable today.
