How much is enough for retirement?

I guess this depends on what country you come from and the circumstances, I am retired, and have been for some time, I was made redundant and was given a small payout and I invested that and am now living on the interest, it isn't much but enough to live on, luckily I owned my own house which is one of the main things that made it easier for me, so it really depends on your circumstances, I wish you well, have fun and enjoy your retirement you have earnt it.
