Can Bacillus F make us immortal?

Achieving immortality has always been a dream of the human race.
But it is a sad fact that one who is born must also die one day.

Today's scientists are eager to discover a way that can achieve this seemingly impossible goal.

A significant event took place in 2013 when a scientist named Anatoli Brouchkov injected himself with a bacteria that he discovered during his geocryologist study of Mammoth mountains in the northern Siberian region of Yakutsk in 2009.
According to him the bacteria had been there for around 3.5 million years.

He named the bacteria Bacillus F.

After the discovery of Bacillus F, the scientist claimed that he got positive responses when he injected the bacteria to mice plants and fruit flies.
Mice who were injected with the bacteria could reproduce for longer period of time, while plants who were modidfied by the bacteria were not attacked by insects anymore.

To prove the effect of this bacteria, Brouchkov injected himself with it.
He now claims that he is able to do more work than others, while never be the target of the common flu in over two years.

So basically I have the following questions on my mind:

Can Bacillus F really turn our dream of immortality into a reality???

How did the scientists come to know that the bacteria is around 35 million years old?

If we are able to achieve immortality, would it be a blessing or a curse?

Thanks for reading the question. I am looking forward to your answers!
