I dream of quitting my day job and visiting all continents of the world
there  are so many ways to travel, y foot, bike, car, train, bus, boat, plane, you could also do a veriety 
Plane is considered the safest right? judging by the fact one is traveling a far distance
Yes I believe so at least for long distance, travel can also inlcude short stays or distances as well
So even if I have to break for ten times so long as I return to my original position, it's considered as travel?
I dont think that is traveling any distances, the word travel is an old frence word travail that means to work
I agree with you. Do you know who made the travel that was recorded?
I dont but according to Websters the word travel is from the 14th century
Wow, that's long time ago. During these period what was the means that was used
I imagine by foot or maybe donkey, travel may or may not be easier today depending on where you are going
