I Was Taking The Web-MD Pop-up Survey And It Asked

I was taking the Web-MD pop-up survey and it asked my age. I'm 72 and don't care who knows it, but my choices stopped at 65 (none for "over 65" or anything like that), or "I prefer not to answer". So I tried just to ignore the question and was unable to do so. So much for accurate research. I will not bother with any of your other surveys if I happen upon them.

What I was trying to look up was any untoward interactions between lithium orotate(recently recommended for me) and melatonin which I have continued to take nightly even though I as now retired from over 30 years of night shift. I find the melatonin very effective and have not had a problem with it.
