Jesse Eisenberg is making the world better in one of the most selfless ways possible — by donating his kidney to a stranger in need sometime next month.

The Oscar nominee talked about his decision during Thursday’s episode of the “Today” show, sharing, “I’m actually donating my kidney in six weeks. I really am.”

“I don’t know why,” Eisenberg added. “I got bitten by the blood donation bug. I’m doing an altruistic donation mid-December. I’m so excited to do it.”

An altruistic donation is when a person donates a kidney, organ or other body tissue to a transplant candidate that he or she does not personally know.
