Reading a fun book called:

"100 essential things you didn't know you didn't know"

One of the interesting things is the doubling of a sheet of A4 and how once you fold it seven times it is impossible to tear. That is straightforward. More interesting is that if you took a sheet of A4 and doubled its height each time as if folding it again and again after 204 iterations you would have passed out of the universe. Halving each time takes you to the lowest size.

It also suggests the character that Moriaty was based on.

Covers the match between Barbados And Grenada in 1994 were both teams were defending their opponents goal!!!!!? Its on Youtube for those who find it surprising.

And stacks of other fascinating anecdotes on maths and the world.
