I have a question. I want to know if there was any modelling done on all the jobs out there and the age groups they employ. Was any modelling done on that? Let's look at the transport industry for one. A lot of them are older people; they stay in that industry. There are going to be people out there who are discriminated against not just about age but about what job they're doing, so was there any modelling done on that area as well? That's all I'm asking.
