Dear friends, In my last message called "precaution" I announced that I had a hepatitis. This information was wrong. Really I had a panchratitis without any risk of contagion. I am giving this information for your tranquility. I have been a week in the hospital but since last Monday (June 5) I am at home and step by step I am recovering my good shape. Best regards Ramon
