Currently repeating `hydrogen-sulfide` is not ideal because the ID/URL has that word duplicated:

``
/pioyi/hydrogen-sulfide/production-of-hydrogen-sulfide
``

I understand that currently perhaps this is the only choice because you want the title to show as "Prodcution of Hydrogen sulfide".

But in short/mid term I want to make scope ancestors show up on the title such sa:

``
Hydrogen sulfide / Prodcution
``

which with the current source will lead to duplication on the title as well:

``
Hydrogen sulfide / Hydogen solfide prodcution
``

So I'd either do:

``
= Hydrogen sulfide
{scope}

== Prodcution
``

or:

``
= Hydrogen sulfide

== Hydrogen sulfide prodcution
``

but not both scope and repeating as current:

``
= Hydrogen sulfide
{scope}

== Hydrogen sulfid prodcution
``


You might want to keep this just "Production" due to scope

One should not forget that our bodies can produce hydrogen sulfide with the help of speicifc bacteria found in our \b[mouth] and \b[intestines]. 

These take advantage of the sulfur found in \b[proteins] that we consume (four aminoacids, the buldings blocks of proteins, contain sulfur).
