So I've been seeing posts and news articles about genes turning on and off (particularly I learned about the gene that allows us to process lactose). Is it possible to manually turn genes off or on? for example the gene that allows us to drink milk, can you go in and turn it back on? I'm not a scientist so I'm not sure how all this works lol.

What is a comprehensive list of poisons that one can build immunity/high residtance to? Is there something that also show an effective way to do this by body size, weight etc?

I have a friend in the exact same situation, about to compete in the next ifbb (I think that's what it is) tournament. How can he breat into this business as well?

What kind of benefits could we see from something like this if it's possible to manipulate this in the human body? Could it cure cancer?
