That's not what we're talking about when we're talking about cumulative exposure, not chronological, not sun exposure over time, which increases your incidence or risk of skin cancer. We're talking about, I think, a multiplicity of exposures, of sources, other than these three particular products that we're examining in this private member's bill. Does the science exist now? Is there a protocol? Is there a practice? Is this happening in industry? Is it happening in government? Is it happening in a regulatory setting?
I'm drawing a distinction here between chronological exposure to one substance and a multiplicity of exposures at one time.
