Time

What its time? Well i cant define it without give it examples with the same word.. Its the magnitude that human create to count the time? Well its very difficult to me explain time, but eventhough that we cant define it, we can see it, in the changes that happen in our environments and in ourselves, for example if something its over, and the changes that happen in our body like change of voice, change of size, wrinkles etc. the notion of time its inevitably linked with the movement of the world in general, the time its a essential item of the society because this is a very important tool of people to make contact with other people, without time i dont know what we would make... or how we would communicate with society. time its divided in past, present and future, the present i think that we never reach it, all moment ends and it turn to past, so where is the present?

i think that present dont exist in concrete because it only have a duration of the mimimum duration of the time, and the future we always think about it but it turn to present and then to past, i think that the only certain moment of life its the past, because we have the memories and the know that we live in that moment and what we did, the past its known but we can not change it, and the future its the unknowns moments that we can change, but we dont know about it, well i think that time its a very difficult topic to discuss because we can explaine what is it.
