In your 20s, crises tend to be about whether you are making the correct decisions for the rest of your life, namely in your job and relationship. In your 30s, work-related issues and break-ups feature prominently. In your 40s, for women bereavement is often an issue. For men, it is still to do with their job but it has moved to "Holy crap, I've got a lot to do". In your 50s, you get features of both early and later life crises - bereavement and ill health. And that continues in your 60s, with retirement-related issues and heightened awareness of mortality.
