Что хотела сказать на русском:

"Один немецкий учёный утверждает, что большая активность приводить к уменьшениею жизни. Этого профессора зовут Питер Аткс. Его мнение кажется парадоксальным, но оно частично правильно. Питер считает, что у каждого человека своя сумма энергии, и что каждый человек должен сохранять как можно больше этой энергии. Можно лениться. Это даже полезно. "

Что получилось на английском "

A German scientist says that more activity leads to a reduction of life. This professor named Peter Atks. His view seems paradoxical, but it is partially correct. Peter believes that every person has their own amount of energy, and that everyone should keep as much of this energy. You can be lazy. It is even useful.
