My super-achievers grandchildren

Wow, I have a family of super achievers grandchildren. First there is the youngest blogger in the world. Then Lewis Chew earned the title of world's youngest drummer with his "almost perfect" drumroll. That is not the end. Lewis Chew also became the world's youngest cyclist, making good use of the new bicycle his grandpa gave him. There is no end to his talent as Lewis Chew also became the world's youngest basketball player.

Not to be outdone, Lewis Chew's cousin, Isaac Low delivered his first public speech and became the world's youngest public speaker.

What next? World's youngest astronauts?
