http://edition.cnn.com/travel/article/30-things-travelers-should-do/index.html

I've done 14 out of 30.
So, I'm not qualified to be 30, according to CNN's journalist. Hahaha.

In the section "3. Take a classic train ride", there is a sentence below.
" In a world possessed by planes and automobiles, there's still nothing quite like a great train ride."
Its world has already achieved in almost all the parts in the United States, where the headquarter of CNN is located.

And, I would like to take up the title below.
21. Eat a hot dog in Times Square

And, though I don't know if it's a kind of things to do in New York's Times Square, I forgot eating hot dog there, when I visited New York last January.

Why is it the worst thing to choose narrow seats?

AirlineRatings names 'most excellent' airlines for 2018
http://edition.cnn.com/travel/article/airline-excellence-awards-2018/index.html

I think that how spacious economy seats are is one of the most important factors to choose airlines when flying between long distance.
when you board an aircraft which has narrow seats in economy class, what happens?

First, it's difficult to go to toilets, when you are not seated on aisle seats.
Second, while eating inflight meal, it's difficult to make a way for passengers who don't sit on aisle seats and wants to go to washrooms.
Third, when neighboring passengers are so fat that parts of their bodies invade your area, it's nightmare.

Based on the ranking, I'd like to choose best airline for my trip.

Why am I concerned about railless train?

CRRC tests ‘railless train’ electric bus in Zhuzhou
http://www.metro-report.com/news/news-by-region/china/single-view/view/crrc-tests-railless-train-electric-bus-in-zhuzhou.html

It's an innovative invention that this rail system requires just white lines in tracklaying. But, it means that the train may misunderstand white substance as a track, which may cause derailment.
In addition to that, I doubt it's possible for those trains to choose a track when passing through branching rails.
I wish CRRC could solve these problems before kicking off commercial operation.

Why is it dangerous to obey neural machines at any time?

Transitioning entirely to neural machine translation
https://code.facebook.com/posts/289921871474277/transitioning-entirely-to-neural-machine-translation/

Recently, self-studying machines have been used in various fields. For example, we can see black and white pictures painted by neural networks more frequently these days.
But, we have to pay attention to what kind of information we should give to neural machines.
False or Biased information may lead those machines to come up with inaccurate answer.
Especially when people believe or rely on neural machines' answer, we have to be care about that.

Why don't they check expansion of visa-free service?

The country that will possibly have more visa-free nations is expected to be
・Smaller country
・Smarter country
・Less threating country

So, I think that Catalonia, if it gets independence, will rank in better position.
Though those who support independence of Catalonia wouldn't notice it, more countries will offer visa-free service to Catalans than to Spain.

But, what I'm concerned with is that every area around the globe will strengthen independence movement after seeing Catalans' success, if they succeed to be independent from Spain.

Why don't you doubt feasibility of a tram extension to the capital airport?

www.metro-report.com

When I boarded Rabat-Sale Tram, I thought that it's inconvenient that the tram hasn't yet been extended to Rabat–Salé Airport. But, it's under planned.
On the other hand, annual passengers of Rabat–Salé Airport is 873,169. So, even if all the passengers at the airport use the tram, daily ridership of the tram is just 2392.
It's approximaltely half of the passengers at Hakodate Airport, to which Hakodate Transportation Bureau(Tram) gave up extending.

Is it possible to extend Rabat-Sale Tram to the airport?

Why can you remember all the structures of each type of sugar?

edition.cnn.com

When I read the article, I thought that the last section of the article would not be understandable for general people except for chemists. Who can distinguish complicated sugar from simple sugar?
So, The article should have said "When you see ingredients on each food , if you find letters listed below, it would be better for you to eat it."

Otherwise, even professors cannot extract which type of sugar is not favored?
