62M going to jail, what to expect

Hi all, as you all know I am going to jail very soon. I was charged for corruption and bribery as a government official. It sucks because I thought they were just gifts and me being me, from where I come from, my culture just takes things like this lightly. Well at least the government didnt charge me for many other illegal things that I did that will remain private for their face.

Anywho, what to expect in jail? I am particularly afraid of my ass being wrecked or people that are very against government officials.

Any tips to survive there? (No I dont want to suck tips there too)
