I think this is also need to categorize the discussion. If usually always love to exercise those older people often travel to some high places, will not be afraid to travel to Tibet, plateau reaction is not very very serious, so can only say that you can consider going.
Not to say that you usually exercise quite good must go to risk this line, after all, the elderly age has been big can not withstand too much stimulation. A while ago is not also because of an old man smoking, others to stop, she was angry angry dead? So this also depends on their own constitution. But if like Jackie Chan kind of I feel there should be no accident. Because he this kind of star martial arts star physique is really superb, although he is not considered to be elderly, but the age is also considered quite old, if every person like his age group are the same as him, I think it is really especially great. It always feels like Uncle Long is omnipotent.
But usually just square dancing, and do not have the kind of habit of going to high places to exercise the kind of old people must not go to Tibet to travel, because you do not know whether you have plateau reaction? If it is very serious then it will lead to all kinds of physical discomfort, in case you are not careful then you will regret for a lifetime. So that you want to take the elderly traveling does not have to go to the bath, you can take her to some mild place to the beach child medicine and what is also quite good, let them sunbathe, enjoy the beach.
Don't take the old man to adventure, despite his post is very good, don't go to the plateau reaction even normal young people can't stand, not to mention the elderly, to be responsible for their bodies, the elderly is a small child to treat the elderly as if they were small children. So it must be careful to treat the elderly.
