Indy:
It sounds to me like you have a high temperature—better let your boss know... ;-)
I dont have a high temperature.
But I am closer to 60 than 50, and have a past history of asthma after a very serious respiratory infection around 10 years ago. I am not currently on any medication for it, but was on a cocktail of expensive medications for several years after that.
I also have mild hypertension, which is under control. As long as I stay on medication, my BP is usually excellent. The only problem is I take an ACE inhibitor.
Does that sound like a sufficient number of risk factors?
