Answer to Question 1

Unless being fed mass from a companion, the pulsars must eventually slow down as their magnetic fields impart spin energy outward in the form of the observed pulses; if the rate they are slowing down is carefully studied, it may tell us when they were spinning much faster, newly hatched from the supernova birth.

This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
