Some mischievous people always there. Last several thousand years, always there. In future, also.

You are the people who are shaping a better world. One of the secrets of inner peace is the practice of compassion.

Sensory experience does not offset the intense pain or pleasure we feel on a mental level; it may distract us, but doesn't overcome it. On the other hand, if we have peace of mind, even negative experiences do not upset us. Peace of mind is also good for our physical health. Medical experts have found that anger, hatred and fear eat into our immune system. Being calm and relaxed is better for our physical well-being.

Misunderstanding may arise by confusing the Buddhist and scientific definitions of death. Within the scientific system you spoke quite validly of the death of the brain and the death of heart. Different parts of the body can die separately. However, in the Buddhist system, the word death is not used in that way. You'd never speak of the death of a particular part of the body, but rather of the death of an entire person. When people say that a certain person died, we don't ask, "Well, which part died?"

A compassionate attitude opens our inner door, and as a result it is much easier to communicate with others. If there is too much self-centered attitude, then fear, doubt and suspicion come and as a result our inner door closes. Then it is very difficult to communicate with others.

A compassionate attitude helps you communicate more easily with your fellow human beings. As a result, you make more genuine friends and the atmosphere around you is more positive, which gives you greater inner strength. This inner strength helps you spontaneously concern yourself with others, instead of thinking only about yourself.

Altruism is the best source of happiness. There is no doubt about that.
