I haven't seen it on a t-shirt but I kinda liked a saying I saw on someone elses web page....... didn't care for the pix that went with it but anyway....
Racing the Reaper!
I feel like sometimes that is truely what we do......
I have one shirt that says: "Merconium Happens""PHAS" in small letters on the front and a large start of life on the back.
I wear it to conferences and the like, I also just got a shirt from a trauma conference I went to in the Big Horn Mtns but it doesn't have any smart assed comments on it, just where it was and a pic on the back of the mountains.....
