I have some friends, colleagues here at the Karolinska Institute and even in the United States and many other countries too, because we are working together as scientists.

We sometimes freeze the specimen with liquid nitrogen, which is extremely cold, you know. This is another technique we use now - but the specimens are not alive.

Of course, today at the Karolinska Institute, I am working with some top experts - even some Nobel prize winners. They have the latest news and I have the technique.

I have the instruments, ideas, technology, computer techniques. We try to create or see something, which has not been known before - just to discover something together. This is always my dream.

It's to surprise people about something that is extremely well known. I mean human reproduction, the human body, nature and so on. To surprise them with a new technique.

I have many times thought I did the wrong thing, but the reason was not to be a medical doctor - it was just to have the information. But then, maybe I was wrong, I don't know.

Human beings, as I know better than most, can get used to anything. Over time, even the unthinkable gradually wears a little niche for itself in your mind and becomes just something that happened.

Words are cheap. The biggest thing you can say is 'elephant'.

Don’t waste your time with explanations: people only hear what they want to hear.

I've worked with a lot of people who are more famous than myself who are terribly insecure.

You can never learn anything that you did not already know

If you can't solve it, it's not a problem - it's reality.

A meaningful life is composed of a series of meaningful moments. If this is what we want, then the ability to infuse each moment with meaning would seem to be a skill worth practicing.

How come regional pandering only works in one direction, right? You never see a Southern politician trying to win votes in New York State by saying, 'I read books and make a mean vegan meatloaf.'

We know there are lots of leaks everywhere. There's nothing we can do about that, except not leak ourselves.

If you're going to steal a car, don't steal a mail vehicle. They don't mess around. I mean, have fun, steal all the cars you want, but don't steal a U.S. Mail vehicle.
