Lee Evans needs our help. The Olympic Gold Medalist and political activist, who exploded all records in the 400 meters at the 1968 Olympics, has been hospitalized with an aggressive brain tumor. The prognosis for the 63-year-old Evans is not good. As his fellow 1968 Olympic activist John Carlos said in an e-mail, “All of our teammates want to go out and say some prayers. All there is left to do is pray.”
