Answer:
Travel, Some might argue and say travel is hard and expensive, others might enjoy traveling and have devoted their life to do so.
Traveling does not mean going on vacations or going to see glam architecture created thousands of years ago, traveling is not just about experiencing new things and meeting new people, its about how to get to point B from point A more efficiently and cheaper. You see many folks travel for business or family matters and sometimes they are spur of the moment things so many have the added stress on how they are going to get there. Sometimes traveling could even be forced or unwanted and doesn't always mean transportation of humans, you can travel with anything thing living or breathing and you could even be doing it right this moment, like an example could be, you pick up a cup from the table and travel with it back to your bedroom, the cup is an inanimate object meaning it is not breathing but you where still able to transport it to a different place with you.
In conclusion traveling is what you make it out to be good or bad everyone does it.
