Nathan is riding his bike on the bike path where the right side of the bike path is for bikers and the left side of the bike path is for runners. Nathan is texting his cell phone while riding his bike and passes over onto the bike path for runners, hitting Mary with his bike, while Mary was running. Nathan hits Mary with his bike and Mary falls to the ground, breaking her right arm. Nathan immediately jumps off his bike and runs to help Mary. Nathan pulls Mary onto the grass, away from the bike path and calls 911. While Nathan and Mary are waiting for the ambulance on the grass near the bike path, there is a sudden car accident on a nearby road, where a car swerves off the road and hits Mary. Mary suffers from 2 broken legs from the car accident. By some miracle, the car did not hit Nathan. After Mary is picked up by the ambulance and cared for by the hospital, she sues Nathan for her medical damages for her right broken arm and 2 broken legs. Mary's medical damages for her broken right arm are $5000.00. Mary's medical damages for her 2 broken legs are $10,000. Question: Is Nathan responsible for SOME or ALL of Mary's medical damages for her broken right arm and 2 broken legs? What is Nathan responsible to pay under the law? What is the legal theory to support what damages Nathan would owe to Mary, if any? Explain
