Why do pilots still go to bathroom without having flight attendant in the cockpit?

Hi. I thought a flight attendant should go into the cockpit when one of the pilots go to the bathroom because of what the German wing first officer pilot did to the airbus plane.

But I was surprised when I saw an Air France A318 pilot getting out of the cockpit and going to the bathroom without having a second person in the cockpit when I was traveling from Paris to Geneva two months ago. Isn't it very dangerous? I thought the rules were changed after that German wings incident?

Does Cabin Crew/flight attended (does is male can do this) is good job for someone who had mild AS, does is difficult? (Ryanair airlines)?

I'm Polish, recently I have read that Ryanair's airlines are looking for candidates for the cabin crew of their planes, in this announcement they were also looking at men, not just ladies. I always thought that the cabin crew was primarily women.

I thought maybe they need men too, just in case some aggressive passenger has arrived, just like in my country Poland, the profession of nurse is usually associated with women, but I know that psychiatric hospitals prefer "male nurses" xD

In this announcement, it turned out that the salary is paid in Euro and not in Polish zlotys.

I wonder if there are any medical requirements required for this position, I know that there are very high health requirements for pilots, and I always wanted to pursue a career related to civil aviation?

Is Newark, NJ a bad place?

I will be visiting Newark, NJ in June for a concert/convention, and i'm curious as to if the city is as bad of a place as I hear.
My hotel is at the airport right outside the Ironbound area, and i'll ONLY be in the downtown area at the Prudential Center. I won't even be leaving the Prudential Center grounds except for when I use Uber and cabs to get back to the hotel. SO i'm just wondering if there's anything I would have to look out for.
