I am a 21 years old boy and so far I have never taken my health as some serious thing in my life. I think that its better to be late than never. I now want to keep a check on my routine form now onwards. How can I ensure my everyday health? Is there some way out that can tell that how much calories I have consumed in a day and how much I have burned? Please detail me all that you can say on this. Thanks and best wishes!
