MIL and FIL are both 80. Excellent health (so far) and normally very sensible people.
They take their caravan away several times a year and their ‘first of the year’ booking is coming up next week.
They say they’re going to be virtually isolated at the site and will avoid people and eat in the van etc. We’re worried that they’re still planning on going shopping together for supplies (we’ve offered to do an online shop or drop off stuff but they say they’ll go when ‘it’s quiet’).
Are they being cautious enough? Their idea of isolation will probably have to include getting petrol, booking in at the campsite etc 
My 86 year old DM has more health issues and has been on lockdown for a few days with Netflix and gin.
