John即将外出旅行，请你根据提示用英语给他写封电子邮件向他介绍你对旅行的看法并提醒他旅行注意事项

Dear John，

I'm very glad to receive your e-mail about your travel plan. I think traveling can be regraded as a kind of sports.It can help you keep heathy while you are appreciating the beautiful scenery.And you can make lots of different friends while you are breathing the fresh air.But before you have your traveling,be sure that you will have a fine weather.And certainly enough,you should get enough clothes in case the weather changes.Well,the last i want to mention is that you should take some medicine with you,and be sure of safeth during the traveling.

Best wishes!

Yours,
