Do our emotions affect our body, our brain function?

Whoa this is probably the area I have spent the most energy thinking about. In my opinion ultimately our thoughts dictate our choices, which creates our world.

Start to look for yourself, keep going back in what or why you chose to get out of bed on that side, to put on those clothes, to use that lotion, to eat that food, to listen to that radio station, to have that job, to have or not have a partner. You see to keep looking at why you choose what you do must come from your emotions/thoughts yes or no? Consider this….
