Consistently, and only counting people who have had strong, lasting attractions to me that I'm aware of, and in order of frequency of occurrence:
1. Second borns with at least one younger sister.
2. First borns with one biological younger brother.
3. Born in March, April, May, or October; occasionally November or September. Once July. Never December, June, August, or February.
4. XSTPs, xSFPs, xNTPs, and my ISTJ, the
only J that I'm aware.
5. Computer techies(engineers, analyst, etc..), athletes, sales force managers, biochemical engineers(or students of the field), most of whom wished to start their own business or already owned one. In high school, it was the athletes and the most vocal in Student Gov. or S&D. There were a couple of guys off the beaten path and headed to jail, and also really countrified guys, some who regularly fished for their own food in local lakes.
6. People 13 months older, 11 months older, and 5 years older. All three have occurred multiple times over the course of my life in strong, notable attractions. Otherwise, no real age patterns that I can recall.
Thinking about all this made me laugh. Funny.
