Aside from standard work, is there way to make money on side from standard work? i.g. if man work 9-5, is there smart and safe way to enduce currency? some say stock, some say invest. cyclists usually smarter than most because of oxygent to brain higher from ciruclatory exercises. what say you then? not for get rich, and not for get fast money, but sustained extra income for paying for bike, fix, maintenance, other not-cycling hobbies, some free time, maybe vacation holiday after few years.
