Probably you haven't work in a science lab.......ever. Your rigid approach is the evidence of impracticality in Muslim thought today. Try dissecting a leech with any science student (girl) ...and then tell me if you were successful in "keeping your gaze lower" while performing the dissection and discussing your lab tasks with your partner..What about comparing the results and analyzing the results?...This is the simplest of examples I'm giving you....Don't even think of dissecting pig , frog etc (Forget about operating on human body...) ... Now please , keep it real and practical.....bye
