I agree completely. Also definitions matter. Currently in the US one of the leading causes of death, if not the leasing cause, is opiods which the CDC classifies as “accidental overdose”. The healthiest people in the US are probably abusing opiods at lower rates and therefore less likely to die from the leading cause of “accidental death”. The study is from sweden but just pointing out that the assumption they make is flawed - “we should not expect a relationship between fitness and accidental death”.
