I know this is probably already being work on but ... wouldn't it be nice if we could create our own robotic (programmable) cells that travel the body looking for other objects that matched their internal database of known pathogens? Upon discovery, destroy those sorry cells!
My little girls play with dolls and love to care for them. They also ask me what I do. Why not merge the two interests? We need more people working on this instead of "medicine" and drugs.
