As there is no god, no truth in religions, and no afterlife whatsoever, every possible human fulfillment can be redeemed only in this life.
Because nothing transcends from this life beyond it, there is no value in principle in life itself. It doesn't matter whether we die today or in 100 years. Measured by the infinity of time, our lifespan anyway is infinitively short.
Furthermore, it is obvious that every animal, including those of the species Homo sapiens sapiens, has much more capacity to suffer than to be happy. This is part of the genetic design of every animal, as it enhances its competitiveness.
Because our life-spans are infinitively short, and because nothing which could be of individual benefit to us transcends from our lives beyond our deaths, and because the likelihood that we suffer is much greater than the likelihood that we are happy, and because, furthermore, our suffering can be aggravated manifold, while all our happiness eventually ends in boredom, it makes sense to assume that it would be better to be dead than alive.
However, the genetic design of our emotional facilities effectively deters us from terminating our lives. Again, this is at the biological base of animal life itself, as it enhances the chances of a species' genes to propagate.
There is no point in lamenting our genetic make-up that prevents us from happily committing suicide because we have logically concluded that it would be better to be dead than alive. The immediate self-termination option is just not realistic as it contradicts our nature.
Instead, what we can realistically strive for, is, that when we die, we have a gentle death. The ultimate gentle death is, of course, to die unexpectedly in one's sleep.
Anything that enhances the likelihood for a considerable number of people to end their lives in such a manner shall be a concern on a political program in a more enlightened society.
Apart from experiencing a gentle death, the only other definite biological value in life is optimal sexual experience. For only during the moments we experience orgasm, we can genuinely forget the elementary senselessness of our existence.
Again, anything that would allow a larger number of people to live a sexually more fulfilled life shall be a legitimate political concern in more enlightened societies.
