Amasios Somatic Markertheory, part 2

where Damasio brings his thoughts together to propose the Somatic-marker hypothesis.The hypothesis is, in part, a suggestion for how emotion and reason interact with each other. What is a somatic marker? How could it help connect emotion and reason/rationality? If you can, describe a typical emotion situation that supports or challenges the somatic-marker theory and explain how it does that.
