We Would Lose Sleep Over the Loss of a Finger, but Not th...

Let us suppose that the great empire of China, with all its myriads of inhabitants, was suddenly swallowed up by an earthquake, and let us consider how a man of humanity in Europe, who had no sort of connection with that part of the world, would be affected upon receiving intelligence of this dreadful calamity. He would, I imagine, first of all express very strongly his sorrow for the misfortune of that unhappy people, he would make many melancholy reflections upon the precarious-ness of huma...

 How Gender Bias Impacts Men

Men—I would like to take this opportunity to extend your formal invitation. Gender equality is your issue too. Because to date, I’ve seen my father’s role as a parent being valued less by society despite my needing his presence as a child as much as my mother’s. I’ve seen young men suffering from mental illness unable to ask for help for fear it would make them look less “macho”—in fact in the UK suicide is the biggest killer of men between 20-49 years of age; eclipsing road...
