People are now expected to work, often full-time, until they can get a pension at 67. What is supposed to happen in three years to make them decline so much that they should be expected to stay indoors?
The current lockdown is supposed to 'flatten the curve' so that the NHS doesn't get overwhelmed by vast numbers of patients needing ventilators. If the situation is now being handled properly, and the curve is flattened, a second wave should be manageable - that was the point of the lockdown. Wasn't there talk of turning taps on and off, or a similar metaphor?
Are the above figures the percentages of people in the various age groups who are expected to die, or who are expected to die if they contract the virus, or who are expected to die if they are ill enough to need intensive care? Or a ventilator?
Without that being clear (and we currently have no idea how many people of any age have contracted the virus, as there are no antibody tests) they are pretty meaningless, other than to show, unsurprisingly, that morbidity increases with age.
Do the figures take into account underlying conditions? If not, then again they are meaningless. A fit, healthy 70 year old with no relevant underlying conditions may very well have a better expectancy than a sick, unfit 35 year old with a lung condition. It's probably the case that more older people have underlying conditions than younger ones, so the variables need to be taken into account, not just the bald figures.
Compelling people of any age to stay indoors indefinitely is a massive step, on a number of levels, and could be the thin end of a number of very worrying wedges.
