It says:

"We have detected that you are accessing this website from outside the United Kingdom. Unfortunately, rights have not been granted for international streaming and downloading of this programme."

typical

I noticed that only British sites do this...why are they so protective?

coz non-Britz steal em

What's it about anyways?

its about how the brain ages... like it made me woooooooooow
and u know ppl thought that neurons don't recover n stuff when they die... well thats all wrong coz they did this experiment on mice and found that stem cells turn into the right type of neurons and so reconnecting the circuit..

+ exercise make ur memory betta

Yeah I know that... exercise makes everything better lol.

innit man...

if we inject stem cells into a mentally retarded persons brain, it may be possible to give them cancer as well... wait is this such a good idea?

^^ but innit as the stem cells differentiate (in this case into a neuron) the cells gain the ability to program its death (apoptosis)...

cancer is a gamble, the more chances a cell has to mutate the more likely it will happen.

yah, thats why stem cells aren't used for treating ppl yet
