I sometimes think most of these issues lie in our head. It is our incapability to watch everyone as humans irrespective of their genders. I have seen so many woman (in fact, young girls) take pride in taking the seat while a very weak old man would stand right across them. I am not being racist in categorizing the old folks. Nor am I calling them incapable. It is just that the human senses need to respond more seamlessly in helping anyone who is in need. We need to raise above being men and woman and start seeing each other as human beings.
