Hope you are having a bucolic bank holiday weekend.

Look what I got out of the library on #cleanairday.

Infrastructure affects concentration levels in buildings but ventilation helps dilute and destroy viral viability seems to be the message from this Scientist ( Al Haddrell).

When was this published? If in the last few years this makes me angry. I know parents are concerned about their children being anxious and want to reassure but if a recent publication it’s misguided. My child was sent home from school with this a few yrs ago. Odd book to select to say the least.
