Putting my money where my mouth is

I do research. I believe in research. Well-done, science-based research. In order to have research results, people need to take part in studies. I spend a lot of my work time cajoling encouraging people to take part in research studies.

Now there is a study that I could take part in. Should I? If I do, there is a chance I might have to have chemo that I otherwise wouldn't.

Should I put my money where my mouth is? Or just shut up?
