The Boston bomber, Dzhokhar Tsarnaev, was today sentenced to death by lethal injection. The jury reached the decision in the city where the killer, 19 at the time, blew up the marathon, killing three and injuring 260. I feel no sympathy for him, but nor do I support the death penalty and I'm constantly amazed by the hash the US authorities make of a method of execution that sounds simple. Here is a list of 46 botched executions since 1982. This one from last year almost defies belief in its amateurishness: April 29, 2014. Oklahoma. Clayton D Lockett. Lethal Injection.

We had a health panic in the media at the weekend. 'Killer disease on rise due to overeating,' said the Sunday Times. 'Most liver transplants by 2020 could be linked to over-eating, not alcohol', chimed in The Observer. 'Overeating sparks liver disease epidemic among Britons', announced the Telegraph. Should we worry? Maybe. Dr Quentin Anstee, consultant hepatologist at Newcastle University – which is working on an EU-funded survey of liver disease – has found that 25 per cent of people 'who are just a bit overweight' suffer from non-alcoholic fatty liver disease. Previously it was believed that fat in the liver wasn't harmful. Researchers at the Chinese University of Hong Kong are coming to much the same conclusion as Dr Anstee.

A GP called Malcolm Kendrick has written a book about politically correct manipulation of medical data – and has cropped up in the Independent highlighting the medical profession's unwillingness to share research suggesting that being a bit fat makes you live longer. Here are two key paragraphs: Despite the fact that study after study has demonstrated quite clearly that 'overweight' people live the longest, no one can bring themselves to say: 'Sorry, we were wrong. A BMI between 25 and 29 is the healthiest weight of all. For those of you between 20 and 25, I say, eat more, become healthier.' Who would dare say such a thing? Not anyone with tenure at a leading university, that's for sure. In truth, this discussion should not quite stop here.

'E-Cigs Time Bomb', shrieks the front page of today's Daily Mirror. Vaping gets kids hooked on nicotine, experts fear. Experts do a lot of 'fearing', it strikes me, but what we don't know – cannot know for years – is whether e-cigarettes will cause long-term addiction to nicotine. Or what proportion of those nicotine addicts will be people who wouldn't have smoked cigarettes if a safer alternative hand't been available. Tiny is my guess. I notice that the Mirror's online version of the story backs away from the panic-stricken splash, actually describing the story as a 'scare'. One triggered, no surprise, by the state of California, which is obsessed with banning anything people might enjoy. Let me keep this short and sweet.

Michael Gove said something startling about dementia in a speech last night launching an initiative called 'The Good Right' at the Legatum Institute. But blink and you would have missed it. If you regard dementia as a friend’s departure from our world rather than an opportunity to bring them closer to your heart, then you miss the essence of compassion. I bristled when I heard that – at first. Mary, my dearest friend in the world, a lady in her 90s, has dementia. Probably. Depending on how you define it.

I can understand why the Tories have ring-fenced the NHS, but if they do want to indulge in a little trimming I know just where to start – with the moron who signed off on the online 'calculator' that assesses your risk of a heart attack. 'Official NHS calculator predicts when you will have a heart attack,' says a piece in today's Telegraph. Actually, it doesn't. Nor does it pretend to. But the NHS can hardly complain about being misrepresented for clickbait, since – even if you report its claims accurately – the 'calculator' is nothing more than an expensive PR gimmick.
