The lack of standard scaling of amount of activity breaks this chart. Rock climbing is given as roughly the same death rate as heroin addiction: 0.0145% vs 0.016% per year. But the chart counts 100 years of heroin addiction versus only one year of rock climbing and so misrepresents the risk by a factor of 100.

Also otherwise missing units of time for many of the activities.

Fantastic point. This is a work in progress so I can address it. Many thanks for your thoughts.

Maybe you can look at micromorts, it's a unit of risk designed exactly to make these kind of comparisons.
