Thank you.
The other question I want to ask is related to that. Using the calculation method that our colleagues opposite have used, that is to say the number of workers per person receiving Old Age Security, we may suppose that the number of workers will be lower in 2030. I'm not saying we'll eventually have to do nothing to adjust, but if we do nothing, based on that same figure, the number of workers will begin to rise relative to the number of people receiving Old Age Security, will it not?
