There are so many comments of mine on the other video that i'll write here:
No I don't have kids but I want to adopt one day. There isn't a moment I don't think what I would do if that situation comes.. I know if I was dying I wouldn't mind dying but with somebody else I don't know! That's why for now I ask for new alternatives.. And there are: "cells and human tissues culture, bacterial culture and protozoan studies, gas chromatography and mass spectrometry, radio immunology study/essay, pharmacology quantum, electronic simulation (CAMM), mechanical models, databases, clinical and epidemiology studies, human placenta (which is thrown away after giving birth), etc" That's what I've read on spanish websites, written by pro animal's rights people, I don't anything about it, I tried to translate it but scientist must progress like they did it in the past and have new answers.
