To begin with (mysle, ze tu powinno byc THE) prehistoric, ancient times full of divinities, through THE middle ages and first inventions up to a modern age with all its improvements, regulations and norms.
It goes without saying that the quality and way of life HAS changed, but in my
opinion it was not an insignificant change but the great turning POINT for
THE better. So as to clarify the above point, we have to take into
considerATION such aspects of people's life as work, health and
social/family life 'quality' (nie za bardzo rozumiem uzycia tego slowa tutaj).
Most of human's duties are taken over by robots and machines (....for example...?).
Moreover, the 'tools' (jakie 'tools' -) are innovative and much safer than
50 years ago. Second point is the standardized time of working (life? week?)which prevents slavery and 'abusing employees' (nie, nie tak-...abusing OF employees)-(abusing employees- employees who abuse?).
Furthermore, innovative methods, modern apparatus and continuous
inventions in the field of medicine 'still' (moze lepiej...continue to..) lengthen one's (nie za bardzo lubie to 'one's) life and cure
previously incurable diseases.
Changes in this particular issue are enormous when taking into
considerATION schools, food, culture, ways of relaxation, 'entertains' ENTERTAINMENT, sports 'etc' (nie, nie pisze etc-bo nie wiem co masz na mysli). Modern people are much more creative and scientists claim
that nowadays the 'quality of spending free' (cos nie za bardzo) time as well as family relations HAVE changed 'into' (nie - FOR THE better.
It is often suggested that instead of above arguments
people's 'life' (lives?) had better quality 50 years ago than THEY DO today. Opponents claim that people were happier because of 'less stress level' (nie, nie tak - 'lower stress levels).
Moreover, inventive solutions, medical care and 'life regulations' (co to sa 'life regulations?) make life much easier, so that (tu cos brakuje...kto/co jest happier?) happier and of a better quality.
In conclusion, people's 'life' LIVES 'has' HAVE changed. Looking through
above points such as work, health and social (cos tu brakuje - moze aspects?), I'm convinced that this was a great turning for THE better. 'But it was not said' (nie - cos tu nie tak...) that in the next 50 years the quality of people's liVES will (tutaj dalabym ...greatly)improve 'more' (cos to mi nie gra).
