We present an analysis of the kinematics of a volume-limited (20 pc) sample of over 150 M and L dwarfs photometrically selected from the Two Micron All Sky Survey (2MASS). New proper motion measurements and spectrophotometric distance estimates are used to calculate tangential velocities. We combine these kinematic data with spectral observations of H\alpha emission to investigate the age/activity relation for low-mass stars and brown dwarfs.
