    Thanks very much, my current professor for principles of physiology moves so quickly without much visual aid, and it was great to see it broken down like this.

    Sorry, I haven't grown more interested in the subject than before. On the other hand I can say in your favour that you have a really nice voice and could actually make a good narrator! All the best.

    Fascinating although the dialogue is fast paced. So much has been learned and discovered since my days in botany classes 50+ years ago.
