I was Listening to Dr Sarah Jarvis,and she explained about T cells.......they fight infections. Apparently as you age, the number and quality of t-cells declines.....leaving you more vulnerable to any infections. The older you are the more likely you are to catch anything that's around....I guess that's why they are keen for oldies and those at risk to have a flu jab.I'm still not sure about this thing about over 70's being in mortal danger. Are the statistics being warped by the unnatural number of deaths in care homes? If care home deaths were taken out of the formula would over 70's deaths be substantially different from that of others, taking normal percentage deaths of the elderly?
I read Matthew Parris this weekend spouting that the old should give up their triple lock because the country locked down to save them. Not that the extreme number of deaths was caused by over enthusiastic removals of patients to the care homes.
Regarding getting back to normal, i think we are all going to have to decide how at risk we are and adjust our behaviour. I think some will have to stay isolated for a long time unless a vaccine becomes available. This infection isn't going to disappear and we can't expect those who have little risk of being really ill putting their lives on hold any longer.
