what do you think is the best thing in life which is free?

hi,vip,as far as my thoughts,heartful laugh is god given gift and it is unique,which is not known to any other living organisms... Have a funny day.

Hi Viperuzz, For me the best thing in life that is free is being yourself. Being yourself means giving the best in you--to achieve your goals, to be successful, to love and be loved and be the best that you can be! It's really free because the main actor here is you and you have control over everything! Be Happy to be you, be proud to be you IT'S ALL FREE!
