It's hard to be good. says Margaret ...

Fernando Pessoa.

Não tenho ambições nem desejos.
Ser poeta não é uma ambição minha.
É a minha maneira de estar sózinho.


Não sou nada.
Nunca serei nada.
Não posso querer ser nada.
À parte isso,
tenho em mim todos os sonhos do mundo.
Fernando Pessoa.

I have neither desires nor ambitions.
To be a poet is not my ambition.
It is my way of being alone.


I'm nothing.
I'll always be nothing.
I can't wish to be anything.
Apart from that,
I have in me all the dreams of the world.

All major industry studies into bisphenol A's safety, and they number about a dozen, haven't found anything worrisome in low-dose exposures. However, about 90 per cent of studies by independent researchers over the past decade, numbering about 150, have found adverse effects, ranging from enlarged prostates to abnormal breast tissue growth.

The first evidence of the estrogenicity of bisphenol A came from experiments in the 1930s in which it was fed to ovariectomised rats. Some hormone disrupting effects in studies on animals and human cancer cells have been shown to occur at levels as low as 2-5 ppb (parts per billion).
