I haven't rtft and appreciate that deaths gave happened at these ages prior to the pandemic - but it seems that covid infections can impact on heart attacks and strokes many months after the acute infection has resolved.

It's a perfect storm in the UK with the effects of poverty, austerity, cost of living crisis, climate change, pollution, pandemic, stretched NHS, Brexit etc all impacting.
Yes to all the suggestions of living healthily, but in addition to that we need a new government so vote tactically to get the Tories out at your first opportunity.
In the meantime also do what you reasonably can to avoid catching or spreading covid/flu too. Even if you're not especially worried about catching it yourself, it's sensible to avoid given we don't know who it might have long term effects on, and it will reduce pressure on the NHS, reduce pressure on people who cannot afford time off work because they don't get proper sick pay too.
Wear a decent mask (preferably ffp2) and speak to your MP/kids school about HEPA filters in classrooms.
I think lots of people feel because they don't wear a mask for some things there's no point wearing a mask for anything but that's not true - it reduces the chances of you catching covid in a shop or on the bus if you pop one on then. And it reduces the risk that you might pass something on to vulnerable people out shopping or on their way in to their minimum wage job etc.
And wearing a mask encourages others to wear them too - the social pressure to not mask is high at the moment. It's a cheap and effective way to reduce viral spread as we approach winter, we need to look out for each other.
