 II.   Beat the Heat with inspirational pictures / movies – A great film strikes through to the heart of
       what it means to be human, inspiring the mind and moving the spirit. Underdog stories, tales of
       incredible transformation, overcoming immense hardship, and the journey of an average
       person to heroism. Such tales stay with us forever and inspire in us something that we never
       knew was there. These are some of the most inspirational movies of all time. Growing up,
       “Remember the Titans” was one of them. Titans is a movie about winning, perseverance,
       racism, and unity. It’s about seeing beyond the colour of someone’s skin to what lies at the
       heart, who we truly are. It’s about worlds literally colliding and something absolutely incredible
       coming forth from it. (Based on lesson 2)
