Topical Currents is with Harvard educated surgeon Eben Alexander about his near death experience. Five years ago, a rare form of meningitis and a coma created a powerful personal story. Alexander has written, PROOF OF HEAVEN: A Neurosurgeon’s Journey Into the Afterlife. A surgeon for 25 years, Alexander says he discovered the identity of a spiritual guide from his medical crisis. That’s Topical Currents . . . Tuesday at 1pm on WLRN-HD1, rebroadcast at 7pm on WLRN-HD2 and audio on-demand after the live program.
