Well that's some great analysis right there...
It's almost as great as the Myers-Brigg personality test thing going on in the DAI story section of the forums...
There is NO legitimate way to come to that conclusion based on the fact that she's 37 and a doctor.
Yes, there is, on both accounts.
Rationale for Type A:
1.) Doctor-Type B's do not go for demanding or effort intensive work by choice, they lack the drive and irrational dedication. She made the choice to be a doctor knowing full well what it would bring her-demanding, good wages, etc.
Rationale for Cheating:
1.) Doctor = Lots of Education, lots of education = lots of time for booze and bong hits, lots of booze and bong hits is correlated to lots of relationships.
2.) Single at age 37- it is extremely rare to see quality women single past their early 30's. Her history is probably a train wreck-either overinvested in a single failed relationship or has had numerous short term relationships and lacks the ability to get them off the ground.
3.) Cheating is easier when influenced by booze and bong hits.
4.) Cheating is easier when surrounded by external stress factors, like being a doctor.
5.) One one has cheated, they are often much more likely to do it again. Repeat cheats are common.
6.) Pon Farr: When one is in a labor intensive and high stress environment, it begins to develop pon farr.
You're either a stress vent or a rebound, son.
