I saw some ad on the TV - I think for Flora margarine. It was about a guy who as a kid started jumping over the garden wall to keep healthy... something like that... something then about your heart age. I know this was about margarine and polyunsaturates etc. but I'm sure there's a song lyric in there about "heart age"... does your heart age through love or does your heart stay young through love?
Looking for inspiration :-)
