Because we have passed the 'peak' of death rates - a couple of weeks ago now - so the important measure is now the rate of infection which will control not only how busy the NHS is, but also, by implication, the death rate. Taking the death rate as a measure on it's own is not, in my opinion, what should or shouldn't dictate when people return to work!
Hopefully you understand, but shout out if not.
What political reasons am I arguing for - I'm confused as I don't recall arguing for political reasons. Happy for you to put me right on this though, as well as the death rate - that's if you can avoid throwing some more playground insults and discuss like an adult.
