On today's show, the Dr's answer these questions:

1. How does neuroticism interact with IQ? We've all been in situations where a reasonable point of view is met by a barrage of irritable insults. Are people whose emotions play such a major role able to reason in an abstract and measured way, or does high neuroticism knock off the equivalent of 10 or 20 IQ points? Has this ever been studied?

2. What are the uses and limits of trying to create habits? For example, I often try to establish patterns of doing the dishes before bed, going to bed early, showering early during the day, cleaning regularly and the like, but it inevitably falls apart like someone coming off a diet. In what areas are/situations is it worth bothering, and how do I keep of track? How do I alter the CB amd make my conscious priorities into my nervous system's priorities too?

3. My husband had an affair last year, but we are slowly working through things ourselves and taking steps to save our marriage for our children. 1. How can I get over the feelings of inadequacy I have in my marriage post-affair? It's been almost a year since I found out and I still bring it up in arguments. At times I use it as my trump card and win our arguments as he feels bad every time I bring it up. Yet I can't bring myself to stop doing it. 2. How can I let go of the jealousy and resentment towards his affair partner? They are still in contact and remain friends. I find myself checking her social media accounts and obsessing over her, and I want to stop.
