Very rarely Asher. Living in sterile environments is a significant loss to one's natural immune system. I generally carry paper plates and cups with me. Only eat very well cooked hot food, when I do. Water is always mine. I go to meet people, primarily. The food is just an excuse to pay the bill.
Medicine comprises a significant part of my travel weight. Along with its documentation and prescription.
Regards.
p.s last trip to a place, Ayesha ate seafood on the last day of our stay. The journey back home is better forgotten. She was in hospital for 3 days!!
