Crowd Surfing Grandmother Viral Video Surprises Commuters With Athletic Performance

When this 86-year-old grandmother came across a group of baying lads on a packed commuter train, she had only one response.

To the surprise of onlookers, she limbered up and crowd-surfed her way down the busy carriage.

And when she finished, she even did a headstand for good measure.

Watch the video, above.

The woman - whose name is not known - simply walks away from the group after her spectacular performance.

Life goals for all of us.
