When he's not solving cosmic mysteries or fine-tuning medical tech, he’s probably somewhere far from home—he’s visited more countries than he’s had birthdays, and intends to keep it that way. He also speaks multiple languages, including Swedish—which conveniently happens to be Sacred & Profane’s most-sung language after English. Freddy also enjoys skiing, tennis, board games, computer games, and books.
