If you RTFT you'd have seen the article which included:
"Meanwhile, the health secretary, Matt Hancock, tweeted: “We have strongly advised all over 70s to follow social distancing measures. However, there is no ‘blanket ban’, and the suggestion that the clinically vulnerable “include ‘people aged 70 or older regardless of medical conditions’” is wrong and deeply misleading.”
"The British Medical Association’s chair, Dr Chaand Nagpaul, said any proposal to impose stricter social distancing for those at higher risk – essentially quarantining – based solely on age would be “both unethical and illegal”.
"That prompted some on social media to point to advice published on the government website on Friday, which includes the words: “Clinically vulnerable people are those who are: aged 70 or older (regardless of medical conditions) ...”
When contacted, the Department of Health and Social Care said the over-70s “are not included in the most at-risk group (extremely clinically vulnerable), who have been told to isolate for 12 weeks”.
So, some incorrect info went out initially and was retracted. So for most over 70s, the guidelines apply the same as anyone of any age.
