That would bring another set of problems. How would I explain an income with no visible means of support ? An Antique Shop would probably be the best idea and contact in the past with a sort of Fagin type. All those pristine antiques would probably attract attention. What about if you return from the past carrying Bubonic Plague or the future with an unknown desease ? Would you like to be reponsible for the deaths of thousands, maybe millions of people.
This Time Travel lark is bringing more questions than answers, I think I will get on with the present.
