it seems so random, I was super fit and healthy, covid wasn't awful for me but the recovery was nearly a year long and it affected my heart and lungs for a long time after.So strange the way covid has forever devastated the health of some people, yet for others, myself included, it was like a mini-flu or cold. Not pleasant but manageable. My next door neighbour was taken away in an ambulance with it but recovered well. I can remember being terrified of getting it because I have mild asthma and other health conditions, but I didn't even have any trouble breathing on the 2 occasions I had it, just felt congested. I did get chest pains but nothing was found to be wrong with my heart so it seems like that was mostly anxiety. A TV host here in Ireland said on TV that it seemed to be a lottery, how people were affected. He was OK during and after it but he had a lady on his show whose father had died from it and he wondered why that man and not him, what was the difference? He surmised that there was no discernible difference and that it was just a lottery.
Derek wasn't a small man, going by the amount of weight he lost while sick, I'm nearly sure he was massively fond of a tipple too (allegedly) which would had added a co morbidity
