For instance, Marianne Legaton argued that at younger ages and throughout the lifespan, men are more likely to develop disorders, commit suicide and die violently than women (Legaton). These vulnerabilities were documented with case studies and supported by research focused exclusively on gender differences. Also, Legaton noted that there are “poorly understood — and underappreciated — vulnerabilities inherent in men's genetic and hormonal makeup” (Legaton). This suggests that there are still more opportunities to learn more about the differences between men and women in terms of weakness and strength. Nonetheless, it is clear that men are subject to trials that extend much further than just hormones and pain thresholds; moreover, this further exemplifies the issues with characterizing women as a weaker sex in society.
Diane Halpern , in her book Sex Differences in Cognitive Abilities , argued problems with sex vs. gender terminology: "I cannot argue (in this book) that nature and nurture are inseparable and then... use different terms to refer to each class of variables. The ...biological manifestations of sex are confounded with psychosocial variables.... The use of different terms to label these two types of contributions to human existence seemed inappropriate in light of the biopsychosocial position I have taken." She quotes Stephen Pinker 's summary of the problems with the terms sex and gender: "Part of it is a new prissiness -- many people today are as squeamish about sexual dimorphism as the Victorians were about sex. But part of it is a limitation of the English language. The word 'sex' refers ambiguously to copulation and to sexual dimorphism..."  Richard Lippa writes in Gender, Nature and Nurture that "Some researchers have argued that the word sex should be used to refer to (biological differences), whereas the word gender should be used to refer to (cultural differences). However, it is not at all clear the degree to which the differences between males and females are due to biological factors versus learned and cultural factors. Furthermore, indiscriminate use of the word gender tends to obscure the distinction between two different topics: (a) differences between males and females, and (b) individual differences in maleness and femaleness that occur within each sex."
