Inside your chest, a bootcamp is pumping out trained killers (and it’s called the thymus)

Meet your new favorite organ, the thymus. Scientists have since discovered a whole world within this little wad of tissue in your chest – a complex system that trains and equips some of your body's most important fighters against disease.

Jarrod Dudakov, professor of immunology at the Fred Hutchinson Cancer Center in Seattle, explains how the thymus can help us understand why our bodies get worse at fighting disease as we age.
