Congrats F#m!! And all the other #ms too
That looks a very interesting course Maizie. Are you doing it as part of a degree, or are you choosing modules that take your interest to study just as a "hobby"? - I use the term loosely!
Well, both, really My long and ludicrous educational history is that I did a full-time biology degree at the age one usually does these things. I had dropped all the 'boring' not-science subjects as soon as I could through school...by the time I finished my biology degree I began to think maybe some of that stuff might be interesting. I mananged a year and bit after finishing uni before the lack of learning got unbearable, and signed up with the OU. Did a BA mostly based on classical studies and almost done a BSc based mostly on physics. Over that time, I've come to realise that pretty much everything is interesting if you look at it the right way, and learning is what I love and what keeps me sane (really, if my head isn't occupied with something it finds something to occupy itself with, not always entirely healthily; Mr Maizie says can always tell when it's near time for the next OU module to start as the few months off are taking effect!!)
Thing is, the very bestest module of my biology degree was 'the epidemiology of infectious disease', and I loved it so much I was considering further study in epidemiology. Didn't happen, but then a couple of years ago I discovered that the University of London distance programmes include epidemiology. The last module of the physics was not enthralling me, so instead of sticking it out (this is all for fun, remember) I dropped out and leapt over to this module. Has made me realise that I really really did love all that stuff. Looking at whether finances, etc, will allow that further study to finally happen...
Of course, this does all come back nicely to the same problem I have with music - I have motivation but I don't have direction. There's nothing to stop me just studying stuff on my own, but the structure of a curriculum (or teacher or someone or something) telling me what to look at next is what I don't seem able to cope without!
Ah! I understand completely since my Biology degree incorporated 2 units of Parasitology (and associated diseases) and Plant Pathology (even more diseases) and they were quite the most interesting units. Good enough reason for you to drop the Physics and leap to the epidemiology.
