..ich werde mit ernster Miene und in Lyrik antworten.

Life is like milk. The durability is limited. Like the universe maybe extends over our time, the main ingredients of life and milk tend to separate from each other.
If milk is in a glass and it will not be stirred up from time to time, the watery liquid will separate from the firm and the milk agglomerates, building clusters of fat. If it is stirred up the whole time, it depends on the duration and the intensity of stirring and the addition of ingredients when the milk becomes sweet cream or salty butter. If you add no ingredients at all and stirr with balance than you do not change the flavour for a long time, if you do this in cold environments even longer, but you cannot avoid the sour taste at the end and the final decay.
