As a non-medical doctor having a discussion with a fellow non-medical doctor to humor curiosities:
Are you talking to someone other than Yvain, about whom you wrote this remark?
It was written to Yvain. I was under the impression that Yvain was studying psychology, not medicine. Now that his website link has changed, I'm not sure there's a way for me to look this up.
P/S/A: There are single sentences which can create life-changing amounts of difference.
