Are or is?

Second person plural, therefore, "are" . . .

Thanks.

But why?

I disagree. The subject is "each"--singular.

The sentence should read:

There are reasons each of us is born.

It would be better if you said:

There are reasons why each of us is born.

Right. This can be easily understood.

There are reasons why we are born, this is not one of them.
