Safety and Security is human instinct- so the species can survive. Women’s brains are fully developed around age 25 and men around age 30. Therefore, my opinion is, anyone under those ages are more likely to be adventuresome. Prior to my children meeting the fully brain developed criteria, I wanted security. Now that they meet the “they finally have a brain” criteria and I am a bit more than middle aged- young people might say over the hill, I am seeking adventure.
