I cannot wait until retirement when I can stop employment completely. 
Yes, I don't blame you. How many more years do you have?
Quite a few, and anyways many people are starting to put this off and just stay in pre-retirement.
Yes, they are. I think a lot of people can't afford to retire. I have 14 more years of work myself. 
Many choose to retire when they become eligible for private or public pension benefits
Well, that makes sense. It would be tough to live with no income at all. 
Sometimes people are forced into retirement by illness and physical conditions.
That would be awful. I hope they have some kind of benefits available to them. 
Retirement pension is considered a right in most societies
Well, I guess we do all pay into it when we work, so that makes sense.
