208: Arrogant/cocky people, Epidemic of anxiety, Evo psych of suicide

On today's show, Dr. Lisle goes over these questions:

1.I have a brother-in-law who is mildly successful, makes decent money. he thinks he’s the most intelligent and successful person. He constantly finds ways to brag about how well off he is and how he is just better than everyone. How does one deal with a person like this?

2. I would like to understand this epidemic of anxiety that is happening these days. What is happening? I have 5 adult children and they are all thriving, successful, socially contributing adults ranging from 20 - 37. 4 of our children and 1 daughter in law are all suffering from high levels of anxiety. 2 of them are taking medication for it. I have taught meditation for several years now and I see it in the classrooms with children even as young as kindegarten. They suffer with being able to fall asleep and have trouble 'letting go' and just relaxing. Their anxieties are different among them. The girls seem to get anxious about general life situations and the boys are more anxious about every ache and pain in their bodies being some sign of a horrible disease. I'm so confused as to what's going on in this world that so many people have anxiety and how as a parent can I help them. 

3. If mild depression is an uncomfortable feeling that prompts us to evaluate our behavior, in some cases, which would be a positive move to make if we need to make adjustments, how would a more serious form - including suicide - be evolutionarily beneficial? Is this a helpful response gone awry due to more than tolerable social conditions? Do you think we have more depression today than in previous decades, centuries, or civilizations?
