Straight talk.
If you say HPA supports your figure of 1.6%, that is a deliberate lie to conceal the scale of the problem.
HPA STATES 5.3%.
Not for London, but overall for England and Wales.

As an average for ages 15 to 44, if a steady rise from zero, at age 44 it will be at 10.6%.
(If the rise is not linear, that will be an underestimate.)

10.6% will be a great underestimate of the proportion who have succumbed because by age 44, half have ALREADY DIED.

And the figure will go on rising for another 30 years.

1.6% is a lie Royston.
