Apparently, hosting a TV talk show is hazardous to your heart health. In A Barbara Walters Special: A Matter of Life and Death (9 p.m., ABC/Ch. 4), the woman behind "The View" talks about her own heart surgery, and talks to talk show hosts David Letterman, Charlie Rose and Regis Philbin about theirs.
Of course, running a country and comedy can cause you trouble, too. Walters also interviews former President Bill Clinton and Robin Williams.
