"New Scientist Magazine reports on findings that suggest that delaying fatherhood may increase the risk of fathering children with disorders such as Apert syndrome, Autism and Schizophrenia. The article reports that 'although there is a big increase in risk for many disorders, it's a big increase in a very small risk. A 40-year-old is about 50 per cent more likely to father an autistic child than a 20-year-old is, for instance, but the overall risk is only about 1 per cent to start with.' In other words: time to start mating before those tadpoles turn into toads."

    >> we're growing our population exponentially
    That is no longer true. Population growth rates globally, and especially in Western countries have been dropping for years. In some countries, such as Japan, Russia, and Germany, it is negative.

    -1 misleading.

    For every child that's not been born in Japan, Russia, and Germany, a dozen have been born in India, Indonesia, Nigeria, or even China[*]

    Population growth rates globally have been dropping, indeed, but whilst that rate remains above zero, even by the tiniest fraction, we've *still got exponential growth*.

    The greatest shortcoming of the human race is our inability to understand the exponential function. (google that)

    [* That dozen figure is completely pulled from arse, it's probably enormously higher, probably three figures, I'm just playing it safe.]

      Imagine this equation:
      y = 2x

      As x (time), increases, y (population) increases. In this function the growth rate of y is ALWAYS above zero and constantly decreasing. This is a linear function, not an exponential one.

        Nope, that growth rate tends to 0.

          Oh, and did I mention that the greatest shortcoming of the human race is our inability to understand the exponential function.

            Do you know of any other species that is better at it? Any other species that can do math at all?

              Out of the species that have developed birth control - all of them apart from the humans.

          You are correct. The growth rate tends towards zero.

          It also always stays above zero. And it is also not exponential.
