Elderly man's hilarious reaction to finding out his real age

This has to be the coolest Grandpa ever?!

Clearly, he’s lost track of time and isn’t quite sure of his age, so when he’s told to guess his age, he gives himself some credit and starts off young.

But as he starts guessing and gets older and older, his reaction when he realises that he's 98 is simply gold. He didn't hold back and used some pretty colourful language to express his shock and surprise.

For me, the best part of the video is when he says, 'I’m going to be an old man'. I think he’s already there! You’re going to love this guy's attitude and outlook on life.

You're only as old as you feel, right?
