I am a volunteer subject in a medical research study. I must drive about 30 minutes each way to the lab every 2 weeks and have my blood drawn. I hate having blood work but I do it when necessary.
I agreed to be part of the study because I figured I would be helping medical science. After my third visit to the lab they paid me for three visits. I was surprised and even considered the payment “wrong”. I was willing to do it for free – for science.
How much would someone have to pay you to drive that far, sit in a lab for an hour, and have your blood drawn? $20? $50? $100? More? Less?
