Wonderopolis wonders.

This is a presentation about my wonder and if you flick through it then you might find some new information and 3 facts that I like are:
Over the course of a year, your heart would beat about 42,048,000 times!
If you live to be 80 years old, your heart would have beaten approximately 3,363,840,000 times!
your heart beats about 4,800 times per hour.

Hope you leave comments
