What ARE YOU going to do in 5 minutes. 

Well nothing, I'm going to relax and I'm going to talk with my friends.

This looks like a job interview question. Is this a job interview? Will you hire me in I answer? 

But, honestly, I dont know what I will be doing even in one year, not to speak of five. Probably, I'll be working hard and do whatever other people do in their late 20s.

Counting my wrinkles and remembering how I got each one.

A good question and I agree with Three Seven it sounds like an interview question which it is.

I ask this question once in a while in an interview.  

Anyway, I don't go that far as I take a day at a time. 

I will make my dream come true. So, i will try do something to make my life better. In five year,many thing i will do. But, i just try it. Mybe,i will be fail. But, i will try again. So,many thing in our life can we some do.
