If you read my posts without assuming I'dm'fearful' or a lockdown lover, you'll see that what I said is that it's worth listening to senior doctors (the one in the article, plus Whitty/Vallence etc) no that some activities reallynare too risky.
Define 'too risky'. Risk assessment is notoriously subjective.
And as I and others have said, most of us - including no doubt 'senior doctors' - don't avoid all activities because they are 'risky'. If we did, life would be pretty dull.
With a highly prevalent infectious disease, there is no useful indication (like smell) that the room is a risk, and even one exposure could be enough
"Highly prevalent"? Maybe 1 in 200 people has the virus. Most adults have been vaccinated. In the unlikely event they did catch it, chances are they'd be fine.
But obviously, those who decide that this risk is not worth taking are absolutely free to avoid crowded pubs during big rugby matches. Or any other activity they or 'senior doctors' deem too risky. However, they will also have to accept that many others will assess the risk differently and there is little point complaining about it.
