"Interviewing Ronald Reagan," Frank Giles once recalled, "and unable to extract anything but bland platitudes, I asked in desperation under what sign of the Zodiac he had been born. The answer was Sagittarius. 'And what do Sagittarians do?' I said, not through any curiosity but because having started it, it seemed impossible to abandon the unlikely dialogue. The smile widened still further. For Reagan it was equivalent to being presented with a one-foot putt to win a match. Expertly he stroked the ball into the cup. 'I guess you could say they go around doing good to people.' Only later did I realise that in fact his sign was Aquarius."
