Although we can;t change our destiny, we can make our lives easier by depriving ourselves of various diseases which are connected with unhealthy life-style. So we live just once and so we should eat and drink our favourite foodstuffs and drinks, but we should also know when to stop. Why not to have a chocolate or other very tasty sweets? Of course we can have this pleasure, but then we should do also something useful- running, riding a bike to get those calories out of our body and everybody will be satisfied. We will be happy that we;ve had a pleasure by eating that delicious chocolate and our body will be also satisfied, because we;ve done something for its health.
In conclusion I think we all should eat and drink what we like, but we should also do some physical exercise. When there;s a balance between eating and doing exercises than everything is OK and everybody is happy, because noone is deprived of anything delicious.
