British Prime Minister David Cameron is making one final appeal to voters his age and older to think of the ramifications of a "Brexit" for future generations.<br />"Brits don't quit," Cameron said Tuesday just outside his Downing Street home.<br />"We get involved, we take a lead, we make a difference, we get things done."<br />He said that remaining in the EU was good for Britain's economy, security and international standing, and warned that a Brexit would be irreversible.<br />"We will be better off inside Europe.<br />To put it as clearly as I can our economic security is paramount.<br />It is stronger if we stay," Cameron continued.<br />A record number 46.5 million people have registered to vote in the referendum, according to figures published by the British Electoral Commission on Tuesday.
