A few weeks back I wrote an article about how high the risk of dying from covid is. I mentioned that a senior representative of the World Health Organization (WHO) had recently said that the WHO’s best estimate was that roughly one in 750 people who get infected die of the disease. I also mentioned a study published by the WHO, authored by professor John Ioannidis at Stanford University, which was based on antibody data. That study estimated that the mortality rate for covid was around 0,23% overall, which would mean that roughly one in 430 people who are infected overall die of the disease, and 0,05% for people under 70, which would mean that if you’re under 70, the risk of dying of covid is about one in 2,000.
September 2020 was the least deadly month in Swedish history, in terms of number of deaths per 100,000 population. Ever. And I don’t mean the least deadly September, I mean the least deadly month. Ever. To me, this is pretty clear evidence of two things. First, that covid is not a very deadly disease. And second, that Sweden has herd immunity.
In an earlier article we debunked the claim that exercise will help you lose weight. What about whether exercise will help you live longer? Now, don’t get me wrong, I am certainly not anti-exercise. There are lots of studies showing that exercise has many and varied health benefits, from improving muscle strength and balance, to decreasing the risk of fractures and delaying the onset of dementia. But will it help you live longer? And if it does, how much exercise should you be getting to maximize longevity? Are the famous ”10,000 steps a day” and ”half an hour a day” recommendations enough or should you be doing more than that?
