Occasional reflections on Life, the World, and Mathematics

Every three minutes


From a Guardian article on a new theory about the aetiology of Alzheimer disease:

It is thought that this year one person every three minutes will develop dementia.

It’s hard to explain statistics in a way that they feel real to people, but is “one person every three minutes” really a useful way to think about a disease that develops gradually over many years, as opposed to, say, muggings? Perhaps they meant to say “one person every three minutes will be diagnosed with dementia”.
