Just last night I was thinking how the world mostly divides into half full and half empty people. The former tend to see opportunity in things while the latter tend to see scarcity and hold onto what they have got. One represents growth and change, the other stagnation and eventually death.

If ever there was a reminder of the folly of resisting change it is the attempts by the government of the time in Britain to resist votes for women and to see the actions of the suffragettes as effectively those of terrorists.

BBC News Online has some amazing covert photos, taken by the police of the time, of some of those suffragettes. Do take the time to look at the full set of photos - amazing.
