Your contribution is crucial for this project to continue

Our work is absolutely independent, we are not sponsored by anyone and no one has ever hindered us.
Obviously, human and technical resources have a cost that grows in proportion to the amount of data, so our already limited budget at the beginning has become unsustainable over the months.
For now, donations and advertising revenues cover 25% of the costs, but we keep working because we are happy to receive many statements of esteem from newspapers, university researchers, doctors and people who follow us.
Your donation makes us very happy both for the financial help and for the fact that you like and trust our work.
We hope to continue to deserve your support.
