In the First Letter of Peter, he says that women …are "weaker." I, being a female who is totally into women’s rights, am troubled.
Pope Peter was right
1 Peter 3:7 Ye husbands, in like manner, dwell with your wives according to knowledge, giving honor unto the
woman, as unto the
weaker vessel, as being also joint-heirs of the grace of life; to the end that your prayers be not hindered.

Sex differences in humans
**Sexual dimorphism **in humans is the subject of much controversy, especially when extended beyond physical differences to mental ability and psychological gender. (For discussion, see sex and psychology, gender, and transgender.) Obvious differences between males and females include all the features related to reproductive role, notably the endocrine (hormonal) systems and their physiological and behavioural effects. Such undisputed sexual dimorphism include gonadal differentiation, internal genital differentiation, external genital differentiation, breast differentiation, muscle mass differentiation, height differentiation, and hair differentiation.
Externally, the most sexually dimorphic portions of the body are the chest, the lower half of the face, and the area between the waist and the knees.[24][25][26]
The basal metabolic rate is about 6 percent higher in adolescent males than females and increases to about 10 percent higher after puberty. Females tend to convert more food into fat, while men convert more into muscle and expendable circulating energy reserves.
Females (on average) are about 52 percent as strong as males in the upper body, and about 66 percent as strong in the lower.[27] Males, on average, have denser, stronger bones, tendons, and ligaments.
Males dissipate heat faster than females through their sweat glands.[citation needed] Females have a greater insulation and energy reserves stored in subcutaneous fat, absorbing exothermic heat less and retaining endothermic heat to a greater degree.[citation needed]
Males typically have larger tracheae and branching bronchi, with about 30 percent greater lung volume per body mass. They have larger hearts, 10 percent higher red blood cell count, higher haemoglobin, hence greater oxygen-carrying capacity. They also have higher circulating clotting factors (vitamin K, prothrombin and platelets). These differences lead to faster healing of wounds and higher peripheral pain tolerance.[28]on the other hand
**
Species with larger females than males**
In some species such as insects, spiders, many fish, birds of prey and certain mammals such as the spotted hyena and the blue whale, the female is larger than the male. Cases where the male is larger than the female have been studied as well,[11] and require alternate explanations. As an example, in some species females are sedentary and sparsely distributed, and so males must search for them. Vollrath and Parker argue that this difference in behaviour leads to radically different selection pressures on the two sexes, evidently favouring smaller males.[11]
