Life is predefined or a matter of chance but not a choice. I have used this 'funda' many time. The best thing about this 'funda' is that the other person is left baffled. They obviously can't agree to such a thing and eehh at the same time they can't really disagree :D.
How do people do something? They do some action: blink eyes, move hands, speak etc. How do people do some action? They move some muscle in their body which results into action. How do muscle move? They get signals from brain. How do muscle get signals from brain? Chemical reactions! How does a brain thinks? Again chemical reactions. You can not deny the fact that every thing that happens in our body is result of some chemical reactions. Everything happening around us is a result of some chemical reactions.
Consider this: for a given condition, keeping everything fixed; the temperature, the pressure and everything else, will a chemical reaction produce exactly same products every time?
If you think that the answer is 'YES', then your life is nothing but a chain reaction. At any instant the present conditions are product of the previous reactions, which were product of previous reactions and so on till the 'start of time' when the first reaction took place. No matter what you do, or think to do, its all part of the game. Nothing could have happened except what happened. You have no control on what's happening.
If you think your answer to the question is 'NO', then your life is just a matter of chance. Since all the conditions remain same there can not be a logic as to determine what would be the products of a reaction. It has to be random. Everything you do or happening around is result of random reactions. You again have no control on what's happening.
Whether its predefined or a matter of chance life is surely not a choice.
