I know OF 4 people who have been ill with it,
The perfectly healthy runner in Taunton, husband of a friend of mine. 49 years old, Diagnosed COVID, deceased 4 days after diagnosis.
A friend and ex personal trainer, a professional associate of his whom I had met a couple of times, this person, a personal trainer and fitness advisor also, 31 years old, still with respiratory problems and fatigue 8 weeks after diagnosis.
A friend, 52 years old, female, healthy, runner, manager in a clinical research facility, severe fatigue for 6 weeks and sense of smell lost for 8 weeks.
Another friend, living in Manchester, 62 years old female, again extremely fit and healthy, severe headache, sore throat, respiratory problems, thoroughly unpleasant experience for a few days, totally recovered after 10.
The above, plus a doctor friend who was working at the coal face through April to June and has seen a lot of distressing, wholly horrible cases, are enough to convince me that it is really something that I should do my very best not to catch, therefore protecting me and anyone I come into contact with, and the guidelines are for my safety and therefore something that I should follow.
Now, I am not a doctor nor in anyway have had an education that could lead me to dispute evidence, findings and opinions of those who by peer judgement are called "competent in the field" so I have no reason to challenge the guidelines and every reason to do all I can not to catch the thing and spread it around.
Each to their own opinion that can be respectfully listened and responded to.
