It is ok for an 80-year-old man to go to Thailand, but it is necessary to ensure proper travel insurance and health status. Thailand is a tropical country. When traveling, the elderly need to adapt to the high temperature and humid environment. In addition, if the elderly need to take prescription drugs, it is recommended to consult a doctor and bring enough drugs before departure.

In short, when planning a trip to Thailand, the special needs and health status of the elderly should be taken into account to ensure that they can enjoy the trip safely and comfortably.
