Yet why would lips be tender, but to kiss?

Oh gas fire, keep me  warmer  and relaxed
For  frost has bitten and my lips are chapped
I must wear more lip salve but perplexed-
I wonder if wild apes protect their lips?

We were not made to sit by a gas fire
From Africa, our ancestors roamed far,
But did not note the chill of Lancashire.
Nor plan to use a train or drive a car.

Instead of  adaptation   to the cold
We made use of beeswax and sheep’s oil
While men hunted for  pigs,both wild and bold
We women used  rich substance to beguile.

Charles Darwin’s theories may be as far as this-
Yet why would lips be tender but to kiss?
