I don't understand that we are living for earnings or we are earning for living a good life. We are living with full of uncertainty. We don't know when we gonna a die. Before decades people living a healthy lifestyle they were healthy and happy. Now a time we are happy with our materialistic life but we are not healthy. Day by day people are moving on healthy lifestyle but still we gonna attached with diseases. We are working till age of 60 to 70 years to just live freely after our retirement age. But are you sure you will be live 100 years. No right? So why we are not doing something that we work till our 40's - 50's and give ourselves retirement in early stage and live best life because we don't when we gonna die. Work hard so you can live best smooth life whatever time you have and enjoy it with your family. Be Healthy Stay Healthy.
