I'm very conscious, that for certain members of society, if they don't have children/grandchildren, the outcome of the vote is unlikely to impact on their lives, one way or another. I have some sympathy with the guy who said that his grandmother had voted OUT -as was her right- whilst he, and many of his generation felt we'd be better off staying IN. He felt aggrieved that the older generation were potentially making decisions for a world they wouldn't live to see.
I've not ever seen any correlation between age and understandng/knowledge let alone wisdom (ever heard the saying out of the mouths of babes)on political matters (or intelligence and objectivity) and the crucial issues in elections, and here, a referendum which would have been a harder subject to master, so no
If the country can send you to war, allow you to marry, insist you pay tax, and be a law abiding citizen, they can give you the vote
Eta seeng as the seas are unchartered, no one can say what the future will be so older people dont necessarily have the right view...the future is always taken over by the newer generations and thank god for that otherwise the world would be stuck in a rut for eons
