Other interesting facts about Freemasonry include, whenever in Lodge meetings or at the meal afterwards, discussions of a Political or Religious nature are not allowed, this is to maintain the peace and harmony that exists in a Lodge. It is not unusual and happens often that members of different professions form their own Lodges, for example, you will find Old School Lodges, University Lodges, Lodges of Policemen, Bankers, Lawyers Musicians, Entertainers, Boy Scouts, Aviators, Sailors and many more. However times do change and Freemasonry must learn to adapt and accept change, that is inevitable if the Fraternity is to maintain and grow itself, as an example, a Lodge may have started out as a Military Lodge, it may have been started when it was based in a particular depot in the UK, initially you had to have been a member of that particular Regiment to join, but as time moves on that Regiment may have moved on to another town taking all of its members with it, it follows then that for that Lodge to survive the requirement to have been a member of that Regiment is dropped with the effect that ultimately there could be no members of the Regiment left as members.
