He was *almost completely* blind at birth, and he has almost completely lost the ability to distinguish any bright colors (he used to be able to see bright colors like yellow as a child) now.
1) He is 16, which means he still goes to high school. He gets picked up with a cab as part of a special program in our municipality, which he shares with several other schoolgoers that aren't able to go to school on their own. If he is late, it's most likely not his fault. My mom or dad usually brings him to other activities such as horse riding and judo, so they tell him when to be ready.
2) This is really hard to say, as he is only 16.
3) I guess this doesn't apply to him because of his age.
4) He has developed a better sense of time than me, which is probably because he has learnt to be more dependent on this sense, than on natural give-aways about the time such as the sun. He is able to distinguish day (only when the sun is bright) and night by natural light though.
