Mark raised money to build two digital libraries for children in southern India.    And he had some fun doing it!

​

In 2012, at age 42, he ran with the bulls twice in Pamplona, Spain to raise money to build a digital library in a village in India.

​

In 2015, he did another fundraiser for a second library in another village--a "bee beard"--by placing 12,000 honey bees on his face and neck. He was stung once, on his finger.
