My friend's Dad recently passed away. Born in Milan into a family of successful landscape artists, Guido took a different path, pursuing Physics as an author of over 50 publications on energy conversion. Guido still had a passion for painting and won numerous awards. Besides his painting, he found time to be a State instruction director for Soccer referees. Nutella and Panettone were his cravings. Also, he had a penchant for baking. Guido had, on occasion, left Radioactive material from his lab studies in his office. I trust it was of small quantities; no more than a Dental x-ray would emit.
