I don't think it would hit home unfortunately - they think if they get it, it will just be a minor snuffle. There was an interview with a group of young people who were ignoring the guidelines during the last lock-down and one of them said he didn't see why they should give up their socialising because it was only dangerous to the old farts. When the interviewer said that that sort of attitude could result in the death of his grandmother, he said well she's had a good life anyway. Callous or what?
