Nick Miller and his friends gave chase after recognising the former wrestler behind the wheel, and Johnson decided to pull over and say hi to avoid a possible car crash.

And he's glad he did.

Posting a photo of himself posing with Miller on Instagram.com, the action man wrote, "Cool story to share on Easter. After my workout I'm drivin' in my pick up and notice these kids in the rearview mirror screamin' & runnin' after my truck. Thought to myself, 'Should I stop or keep drivin'?' I stopped.

"I hop out of my truck and this kid runs up to me, hugs the hell outta me and says it's been his life's dream to meet me and tell me how much I've inspired him to fight cancer (Hodgkin's lymphoma) and hard core chemo and stem cell transplant treatments.

"He was a little teary eyed and said for months and months all he's wanted to do was find me and say this face to face. I told him what it meant to me to hear this story. I thanked him, hugged him (and his friends), got back in my truck and drove away. As I'm drivin' I start shaking my head (and tearing up) at how fragile life is and how amazing and cool the universe was to make this meeting happen between myself and this special kid Nick Miller."

Johnson added, "Let's always take a moment to count our blessings... cause there's always something to be grateful for. Happy Easter y'all."
