Bubble Boy

Teddy was a bubble boy.
He’d spent his entire childhood in a germ-free environment.
Despite bone marrow transplants, he never grew his own immune system.
So, he stayed in his specially-made room in his parent’s house, and connected to others through his computer and cameras throughout the world.
He had a lot of friends online, one of which who’d ride rollercoasters with a camera on her head, then sending the videos to Teddy.
He loved the thrill, but the dizziness made him ill.
Then came the stroke.
Teddy died with a smile (and a bit of vomit) on his face.
