As  Medical students  we were told that;

'SIPHYLLIS' ,the most dreaded  Venereal  disease of  EARLIER  days, was  a GIFT  of the WESTERN  CIVILISATION and  known as  "ROYAL  DISEASE.'
Of course ,in Modern days , it has lost place to AIDS(More things to come ).
The other Dangerous habits  in the  name of   LOVE and AFFECTIONS ,-are  also WESTERN HABITS  e.g Kissing  and Hand -Shakes.{ the easiest way to get infected through   'Contacts' by  germs and Viruses.-------..

Even to -day,  the words of my great professor of Anatomy Dr. Pashupati Bose [only M.B.B.S} of Medical College Calcutta , India,  reverberates in my ear ,: " YOUR  ANUS  is Cleaner than your mouth and 'Normal Urine 'is better  than so-called drinking water , in terms of  germs , contained in it."

All  apart, Science  now tells that 'Hand-shakes ' can spread  VIRUS  faster than than many other means !
And it has been advised by SCIENCE-World (reported recently) to prefer   ELBOW-SHAKE' to Hand-shakes.
Strange  !  How are  opinions ,- Changing or  Evolving  in rapid progress..
So!  &  Finally ,- think twice  before  the  Kiss or be close  to any one , even Face-to-Face ..
