This comment is not arguing in the spirit of the original comments or my own. Healthy people absolutely do want this technology for the sheer amount of convenience it could provide. Hence the number of science fiction stories about it. The thing is though, assuming that anyone who would sign up for a clinical trial must be sick is an interesting take especially in response to someone else positing that anyone who would do it is stupid or crazy. People can be perfectly healthy and still participate in clinical trials. For lots of reasons to include simply wanting to progress the science.
