53-year-old actor Keanu Reeves looks so young for his age, fans have joked that the Matrix star must be an immortal vampire.

Although Reeves tends to keep quiet about his anti-aging secrets, it’s likely genetics are at least partly responsible.

Reeves’ healthy lifestyle also contributes to his youthful appearance.

He eats small portions of food, and his diet consists mainly of veggies, rice, chicken, and pasta. He stays active by playing basketball and ice hockey, lifting weights, and staying on the move.

He generally adapts his workout routine to fit the character he will be portraying in an upcoming movie. For instance, to prepare for his classic performance in The Matrix, Reeves actually learned Kung Fu.
