“Contrary to what is often thought, excessive hygiene, that is staying in an antibacterial environment, does not necessarily lead to a better health, sometimes it even causes health deterioration. Indirect proof may be that among children of rural backgrounds allergic diseases is less than in urban children. This is because children in the countryside are in contact with a lot more bacteria. You can see that exaggeration is unhealthy in every respect.”

“My mother, whom I loved very much, had trouble with me. I had very good school certificates. But I tormented her with horribly stinky collections. It was not enough for me at home to have a dog, a cat, a canary, a fish, and even a white mouse, which loved to walk around the apartment, although it lived in a cage. I added the protozoa to this menagerie. Traditional definitions regarded these small organisms – such as, for example, amoebae, flagellates, sponges, algae – as single-celled. What in these asexually reproducing animals or plants could intrigue the little boy so much that he permanently endured this abomination (as the mother would say) home?! After all, neither the request nor the threat of this exceptionally tolerant woman, who carried out her home diligently on a daily basis, did not help. A trip to the ponds, or actually to the stagnant at Bonarka – where today is Mateczny Roundabout – were exciting for the little boy. And even more he enjoyed moments when he could watch for hours what was happening in aquariums, jars or cages.”

“In my childhood I had natural interests. I got a microscope from someone, I made a telescope myself, very poor quality, but I could see the moon. First, I wanted to become an astronomer. I read books about astronomy of James Jeans, I even read Arthur S. Eddington, which I did not quite understand. On the other hand, a huge impression on me was made by Jan Dembowski's Natural History of One Protozoan.”

I decided that I would go in the biological direction that I would become a doctor.

“As for the number of people reluctant to me, I guess I fall in the national average. Maybe it's about talking openly what I think? For example, in 1980 an interview with several professors – including myself – was ran by the newspaper Dziennik Polski, very much against the then authorities. We've all been in favor of far-reaching changes, but each of us saw these changes differently. I am a nonbeliever. And there comes the „Solidarity” with holy masses and sprinkling corpses with holy water. I thought that policy of the University, beneficial to the „Solidarity”, was not always beneficial for the University itself. From time to time, friendly people try to affront me, even though I did not belong neither to the youth communist organization neither to the party, neither had I contacts with the communist Security Service. And generally I didn't have herd instincts.”

“I believe – as many scientists – that excessive hygienisation of life is responsible for the development of allergies. We avoid contact with microorganisms, our children live in almost sterile conditions, we wash our hands every now and then. Our immune system hardly comes into contact with bacteria, but it is still in contact with other antigens. So, if the organism gets bored, then these other antigens, completely harmless – a protein of milk, fish, or even strawberries – start to be treated as enemies.”
