In today's show, Dr. Lisle answers the following questions:

1. Are some people more susceptible to addiction than others? If so, why are some people more susceptible to addiction than others?

2. In my husbands family, several members are bullies. Even my husband will join the bully pack if there is any indication they might turn on him. I am highly agreeable and conscience and find I am often the target of their bullying. What is the best 'tactic' to use with adult bullies in families?

3. What attracts people to others from different ethnic backgrounds to themselves? I wish was drawn to women with dark features as there are so many more of these women in the world.

4. People get physically less attractive as they age. They also become less fertile to the point of being infertile. What happens when looks and the prospect of sex are no longer appealing due to age related decline? How does evolutionary psychology explain attraction at this point in life and beyond?
