In his youth Simon exhibited various behaviours, performed miscellaneous thoughts, emotions, and acts, and expressed numerous opinions and ideals. He now pursues other activities, his body looks different and it contains hardly any of the atoms or molecules that it did decades ago. He seems to have irretrievably lost many memories of trivial or boring events; and his mind now contains many things that it did not during his juvenescence. When, or if, Simon gets older, the older version may differ markedly from the current one in what it does. Oh, and he once peed next to Ronnie Wood.
