This is not only happening in Croatia, I'm from Nigeria which we have three tribes. The ratio of wealthy people is very high here so people struggle so as to survive. Imagine how a person that is hawking during the sunny day and person who sit under the hot sun in a main road will look in a year if he continues doing it incessantly.
There are some white men who came to established some companies here, where you will work from 6am -6pm, that is 12hours of interrupted working day, as it is from Monday to Saturday and the wages is just $10 when I converted our currency to USD, imagine, I had also went to work In one of the company before. Believe me, I only used a day and I didn't go the second day because of the stress, I found it hard to wake up from bed the next morning,.
So stress can make people in all countries old when they have overstressed theirselves.
