The Jerry Maguire actress tragically died of metastatic breast cancer in 2020 after a brave two-year fight.
The Pulp Fiction star shared, "He said to me once, 'Because mom passed away, I'm afraid you're going to.' I said, 'Well, it's a very different thing.' And I went through the differences about my longevity and her limited life."
The actor continued, "I said, 'But you know, Ben – you always love the truth and I'm going to tell you the truth about life. Nobody knows when they're gonna go or when they're going to stay."
"Your brother [Jett] left at 16. Too young. Your mother left at 57. That was too young. But who's to say? I could die tomorrow. You could. Anybody can."
Travolta finished by saying, "So let's look at it like it's part of life. You don't know exactly. You just do your best at trying to live the longest you can."
The compelling interview with Hart also went into how Travolta got into flying jumbo jets, as well as his belief in Scientology.
The New Jersey bred Hollywood legend also didn't hold back on his own mortality and admitted he's on his "last chapter" of life. Although he went on to say he feels "eternally 21" despite being in his late 60s.
However, Travolta admitted that his son comforted him by saying, "Well, OK. Do you remember 30 years ago? I said, 'Yeah.' He said, 'Don't you think you have 30 more years in your life to live?' I said, 'Yeah, I do. I have at least 30 more years." He said: What's wrong with that?"
The Gotti actor was stunned that his son was so insightful and admitted, "This is a 10-year-old telling me that! It changed my viewpoint."
Another film he missed out on was the 1978 Days Of Heaven, which Travolta said he couldn't do because he was committed to his hit 70's television series Welcome Back, Kotter.
