A company has discovered the elixir of life. Would you buy it? Why or why not?

Yeah, i would buy. - да, я бы купил.

I'm not afraid of side effects. - мне не страшны эффекты. if everything goes well, then I will live forever.-если всё пойдёт хорошо, то я буду жить вечно.

No, I wouldn't. Because no one did it before and we aren't sure about its advantages, maybe it has some bad sides, so we'll have problems with our health.
