She's in a good age bracket, luckily. So low risk, self-isolating.
The Johnson idea obviously has some good long run maths behind it, but I think it's politically untenable.
They imagine it inevitably will come back year after year. So take the short run pain and receive the long run gain.
The idea is to get all the low risk younger people to get the virus and to create an immune bloc. The bloc will stop the virus from moving freely in future years when the virus returns.
Trouble is, there just isn't a barrier between the young on the one hand, and the elderly and vulnerable on the other. So I think it's likely the number of people dying will reach heights that cannot be sustained by a PM.
