I am pretty sure that a dataset controlling for that would (laughing here) not negate the fact that fewer people who lived past the mean date that are taxi drivers died of a related disorder. That said, suggesting it is related to the career as opposed to, say, the fact that a higher percentage of taxi drivers carry some other set of genes or genetic markers that either led them in some way to become a taxi driver or contributed to a lack of development of the disorder, is pretty weak. In the United States and I think a few other countries the number of taxi drivers which are immigrants from a handful of countries outnumbers any other type. And, the world has changed a lot. Are 1980s cab drivers and 1950s cab drivers and 1965 cab drivers and cab drivers from 2007 comparable? are car service and livery drivers?
