My grandmother lived a happy life in to her nineties…. Her mantra was: Enjoy life - Work hard, Eat well, Be happy! She ate a healthy home cooked food everyday, never bothered to check on the carbs, fats, cholesterol or the calories in the food. We are natives of the coastal region of Karnataka, and our cooking had a liberal quantity of coconut in all its forms (grated coconut,coconut oil,coconut water), in our chutney, sambar or Payasa. My grandmother grew up cooking and eating all these and much more. Concerned about her health we would force her for an annual health screening.

In another two weeks i.e by 8 weeks, the heartbeat of the embryo increases to 150 -170 beats per minute.
