[Гавар'ит жжарам], [см'эй'оца нат сабой'], [дастал исстала], [вашол б'эшшума], [д'элат' ис-пат палк'и].

В словосочетаниях «говорит с жаром», «достал из стола», «вошёл без шума» предлоги сливаются с начальными звуками слов (уподобляются им), за счёт чего те продлеваются (удваиваются).

В словосочетаниях «смеётся над собой» и «делать из-под палки» происходит оглушение последнего согласного звука в предлогах, потому что они стоят перед словами, начинающимися на глухой согл. звук. Если бы слова начинались звонким звуком, дело обстояло бы иначе: [наддомам], [ис-пад лодк'и].

In the modern society the problem of lacking individual and social regard for health is a drastically underestimated one. It only requires a quick mental trip around the world to discover all kinds of irresponsible behavior and alarming condition in personal living routines and in supposedly governmentally supported healthcare. So the situation in some african countries is hardly better than centuries ago in the medieval cities. Meanwhile in a remote region of the globe fatness and diabetes represent a major issue in the USA where both heath defects spreaded widely among younger citizens thanks to the fastfood-preference and the Macdonalds-empire.

But not everywhere and not in everyone's life inconsiderate and shortsighted thinking have the upper hand. Every now and there you get to see a post on instagram about how to eat healthy and you get glimpses at sporty, slim figures of young girls and muscular young men demonstrating their bodies built with thought and care like a sign of not yet total forgetness of people about their own needs and healthy lifestyle. On the other hand plenty of dietary regulations have arosen in later times that in the best case leave us with a slight doubt in the creators sanity, just carnivorous diet prescriptions be named of the long list.

The given quote of a person referred to as Golda Poretsky thematizes the right idea about how to consciously stay healthy. It's total meaning can be subdivided into two partial ones represented by the different parts of the quote. In the first part Poretsky speaks about the necessity of consideration of own wishes by the choice how rigorously to follow through any approved of plan of maintaining or improving own health. Indeed obeying all the steps of such a plan but being constantly unhappy about own doing what good health condition can be achieved? In the end the own body gives certain signals for what is nurturing and what is dangerous for you. The concluding part introduces the notion of spiritual health and advices that both parts of the whole that is human the spirit and the body have to be considered and taken care of properly.
Without question taking your eyes of the concerns of the spirit would result in a decline of your will to live for the spiritual is the true foundation for this will, and thus would have as it's consequence a downing of all the efforts done towards health maintainance. On the other hand a body uncared of can't embody a healthy spirit as the russian proverb teaches.

So everyone is to a big part responsible for their own health and this includes nourishing both body and soul - to lend the words from the Poretsky.
But what exactly is the reality of the relation of the mentioned "should" and the actual "do" around the world?
In the light of ignorance of the better of especially the young generations it is a strikingly alarming necessity to raise awareness of the methods of private health prudence among the citizens of the countries of the world, especially there where public health is a major concern anyway. The possible ways of distribution of made for the issue useful educational content could be the following ones: a section of health maitanining lessons within the biology curriculum at the schools, televisional broadcast with short videos animating to take care of own health partly replacing the commercials, short public talks about the importance of health consideration held by specialists at work places and at universities that are payed for by the government.
