Masturbation, no. At that point nothing has happened. At conception, however, the foetus (and this is the correct spelling, damn it :P) has been started. Of the seven scientific requirements for a being to be deemed alive, at least one is being fulfilled:growth. If you don't agree on these grounds, think of it like this: Think how many great minds could have been destroyed by now by abortion.

1) November the 11th is the date of Armistice day - it marks the end of the First World War. There are two minutes of silence (certainly in Britain) to remember the dead. On the nearest Sunday there is a mass and ceremony at the local memorial, and at the cenotaph in London, to remember those who died both in World War I and in all conflicts which have happened since. therefore it is a very important date to be revered and kept, even if you aren't of a religious persuasion.
