I agree with @tim
Oddly also with the doctor factor, admittedly Uni had required me to sign up with a local GP when I moved into halls, but I hadn’t been to see a doctor for about 5 years previously (not counting a hospital visit or two for bike related accidents )
I’m sure there’s been at least one other person saying they are generally otherwise healthy on here, maybe that’s the problem?! Our immune systems are just too damn good!
Oh, and @Fiona – You’re already better kitted out than me, so that’s probably a good sign!
