Devotee: We may not be able to actually stop death, but while we're here we can at least prolong our lifetime and. . .
Prabhupāda: That also you cannot do. Where is the proof?
Devotee: Well, at the atomic research plants . . .
Prabhupāda: Oh, that is another foolishness, I say. You have not done it. You are simply expecting. Hope against hope, that's all.
Devotee: But they are making different cures for critical diseases that are causing deaths . . .
Prabhupāda: That's all right. But that does not mean there will be no disease. That is already being done by many medical practitioners—better medicine. But where is the medicine that will not be disease?
Tamāla Kṛṣṇa: Gradually we are eliminating, one by one, all the diseases.
Prabhupāda: No, that you have not done. No disease . . . you have increased diseases. You have stopped one disease and increased another. Not stopped, but you have increased another disease.
Devotee: We have to learn, though, how to prevent all these diseases.
Prabhupāda: Therefore you are fool. You have to learn. That means you have to learn, means you are fool.
Yaśodānandana: But we are learning.
Prabhupāda: Don't assert it, that you have done it already, you shall do it . . . as soon as you say: "We have to learn," that means you are fools. And why, you are student, why you are claiming all these perfections? You have to learn. That you have to learn from us.
Brahmānanda: Actually, when I was in Germany, there was evidence of how the scientists increased disease. They invented some vaccine to counteract influenza, and they injected all of Germany with this vaccine. But what happened is sometimes the body builds up resistance to these vaccines and produces another germ. So, as a result, another type of influenza was created, which was far more worse than the previous. It made people get fever for four and five days straight, 105 degrees.
