It's the older people I know who seem most blasé about it all.
That's probably another factor re: people not wanting to stop working etc. If they see older people who are supposedly most at risk refusing to self-quarantine and rubbishing any warnings then they may well think "well, if the people we're supposed to be protecting don't care, what's the point in us taking the hit and staying indoors?" or "They don't care about putting me at risk, so why should I care about them?"
