Your stats make sense...seems the great majority of mankind start life from a liberal posture, niaeve and not yet underdtanding how the World works. This view remains for some all their live, they don't grow nor age away from it. For others, reality and a growing understanding of how the World actually works happens at about age 40. The life view formula seems to  pencil out in the direction of ..." the older one get's the less (nieve)Liberal, the (more realistic) the more Conservative."
