In which I feel bleurgh

So after my couple of days leave (and the bank holiday) I've now been off work sick for the last two days with a cold. Just the usual thing I get: a couple of days of fever, headaches, sore throat, blocked-up ears, etc.

Today I'm feeling less sick (I ate some breakfast today!) but more tired and my concentration levels are quite low, but I'm reasonably optimistic that if I'm feeling a similar amount of better tomorrow then I'll probably be back at work. We'll see.

In the meantime, one thing I've noticed recently: my normal body temperature isn't normal. We have had several thermometers of different types (electronic and mercury) and they have been consistent: my normal body temperature is around 35.9 C, not the usual 37 C. So yesterday, when mine was showing 36.9 C this was actually high for me. The places I've looked talk about the normal range going down to around 36.2 C. Does anyone else have this issue? (As a side issue this apparently has an influence, or is influenced by, your metabolism which may help explain why I put on weight just looking at food!)
