A while ago a favourite mid-life crisis decision for men was to buy a Harley or a Harley-lookalike and head out on the highway (usually draped in Harley gear, including the missus wearing Harley lingerie). A sharp increase in prangs involving older motorcyclists ensued.
I started riding motor bikes when I was a teenager and have owned many. Being 55 with 40 years on the road is not the same as being 55 with 4 months on the road.
That's why I'm interested in the stats about when pilots involved in these kinds of accidents first started flying. Anecdotal evidence suggests that lots of private pilots come to flying later in life (or return to flying later in life after a long hiatus).
