For some reasons, I can explain that the capacity for thanking things depend on our heart. Seeing some old people going and working in the field for half day long and just eating simple food, let's mention nasi, ikan asin, sambal and sayur, can make our heart calm and grateful for life is as that simple. With the capacity of our heart to see the things gratefully is another level of 'Thank God, I am lucky to have this privilege'.
