Nowadays, it is very difficult to find someone who makes brigadeiro or milk pudding without condensed milk, almost always using that ingredient plus sugar, which often produces a sickly sweet mush.

In fact, the whole history of how sugar, or sucrose, entered the human diet is fascinating. It brings together slavery, the exploitation of Indigenous peoples, plantation agriculture in Spanish America and Brazil, and the interests of kings, merchants, and so on. And Nestlé. :)

Why? Scientists are still human beings, they have partake in torture and genocide in the past. "I aim at the stars.. but sometimes I hit London" etc.

We still do it.

I don't know. We live more, but a longer life can also be miserable.
