  We investigate the combined evolution of the dipolar surface magnetic field
(B$_{s}$) and the spin-period (P$_s$) of known magnetars and high magnetic
field (B$_s$ $ \gtrsim 10^{13}$~G) radio pulsars. We study the long term
behaviour of these objects assuming a simple ohmic dissipation of the magnetic
field. Identifying the regions (in the P$_s$-B$_s$ plane) in which these
neutron stars would likely move into, before crossing the death-line to enter
the pulsar graveyard, we comment upon the possible connection between the
magnetars and other classes of neutron stars.
