Ha. Well, I did say I'm not quite as negative as you might've thought! My instinctive reaction will always be extreme caution. Survival instinct or sumat kicking in. I'm exceptionally emotional, I can't deny that, and any perceived threat to my family sends me into overdrive. Then I guess, like many others, the more you learn the better you can judge things. I don't mind admitting if I'm wrong about something. I think there may be one or two things I was wrong to worry about, but who can blame me? We knew fuck all.
It's worth noting as well that even some professors who are now more optimistic have also slightly changed their viewpoints too. This is also why I was so keen early on to stress that people not get frustrated with others who appeared to be doom mongers or overly negative. People get scared. I certainly did, and I still am to an extent. It's entirely normal that some take it in their stride and others are considerably more concerned. I don't think either are right or wrong, as long as those emotional responses lead to the same result - caution and respect for others in following the guidelines.
