Please avoid the mushrooms
Who are the most entertaining of outer-space creatures?
I don’t believe anyone has yet encountered any. All we have are the imaginative creations of earth-based artists (writers, film-makers etc). Some of these creatures are more entertaining than others, but none are from other parts of the galaxy. That entertainment still awaits us.
Avril Taylor, Dundas, Ontario, Canada
• Still hallucinating? You had better stay off those magic mushrooms.
David Tucker, Halle, Germany

Is the world a better place now than it was in the 1950s?

• Since 1950, the year of my birth, the world has always been the best that I have known.

• It has become so for women as the women’s movement has gained momentum. Can’t speak for men.

Emily Winter, Brisbane, Queensland, Australia
