Personally, I think a midlife crisis all depends on the person themselves and what happened in their life.
For instance, I know a lot of friends dads who went out and bought sports cars, made trips to late night "nail salons" etc when they hit about 40. But they all seem to have the same kind of "life" in terms of they starting working young, right out of high school or went to college and worked, got married and had kids young, etc.
Now they are looking back thinking "shit, i never got to do anything fun" and taking the chance now before they get to old.
At the same time I have relatives and friends that are in that age bracket but did enough partying their whole life, their "mid life crisis" is to settle down with one girlfriend
