Things I Have Learned About the Human Body in the Past Seven Months

1. The chest has joints - located in the sternum, connecting it to the clavicle, and connecting the sternum's manubrium, body, and xyphoid process. these joints can be strained, through trauma or strenuous physical activity, such as coughing or, say, intense vomiting resulting from too much damn vodka.

2. The spleen filters the blood and while useful in combatting infections, it is not essential in adults.

3. Trauma to teeth - impact, the force of braces - can result in the death of the tooth, even 20 years later. Or, more specifically, 13-16 years later when a front incisor suddenly turns grayish at the top. the solution? a root canal.
