From the graphs it looks like ambulance drivers and taxi drivers died much younger than everyone else. Hence less death from Alzheimer (a disease famous for happening mostly with old age), so case closed?

I am afraid, there are far bigger confounders than that (which they supposedly correct for): you absolutely cannot be a taxi driver if you experience short term memory loss. So those people may have changed profession at a faster rate than say kindergarden teachers or bakers. Tbf. GPS somewhat changed that but with GPS, the spatial information thing makes less sense.
