Hyperbole are what the media do best! It happens every day. Here in the UK,
a chief medical scientist said with lots of caveats that '*SOME *of the
lockdown measures *COULD* continue for *UP TO* 6 months time'. Headlines in
the paper the next day: UK WILL BE IN LOCKDOWN FOR 6 MONTHS. I don't know
how we as scientists can combat this misrepresentation! At least they are
hyperbole and not bare faced lies e.g. 'I always new this was a pandemic'
or 'Let's inject people with disinfectant'
This is a debate I'd like to continue, if people think there is any use in
