With reference to the medical lecture are you refering to MB, and is he still doing the rounds. I recall he used to wear a bowtie, make jokes which probabably would inappropriate today and he didn't seem to like psychologists from what I remember, although with the introduction of human factors he mellowed.
Lectures on aviation medicine are always worthwhile whoever the AME is, we had an excellent module on aviation medicine by SL (AME at BHX) as part of my instructor's ground school. Really nice chap.
