i have deleted ubaid's post. whatever the argument, i don't see any reason why you must rake up controversial issues in public other than that to show off your knowledge. we have already declined your offer and acknowledged that we don't have experts here. if you have a profusely bleeding patient, take them to a hospital and a qualified doctor. don't try to look up in a book (unless you are a doctor yourself). and there is no need to put such a patient on the roadside and lament, shout, bleat and cry. wayfarers can sympathise and throw in a penny or two, but not every passerby is a doctor. --- i have given my alms (in the form of advice) now take your patient to a doctor.
