...My brother has just graduated from University. He is a lawyer now. What professions are the most prestigious in Russia?

In my opinion the most prestigious profession in Russia is a doctor. Second place is occupied by emergency services and rescue services. In the childhood boys and girls dream to work in hospitals and fire departments. Unfortunately, these jobs are not well paid. If you want to make money you need to become a businessman or work in oil industry. If you want to be an engineer or manager you need to get a university degree of course. But without a university degree you can still be a worker at the oil plant. I would like to go to college because college graduate has wider choice of different jobs in comparison to those who did not finish college. What cities are you going to visit during your trip? In what month are you going to start your trip? Will not it be too tiresome to ride a bike for thee days?
