“they inhale saltwater that contains small marine micro-organisms called diatoms, which means they suffocate and then drown. These diatoms travel through the blood stream and are deposited and preserved within the bone marrow of larger bones.”
That makes no sense! Once someone drowns their heart stops which means all circulation stops with in minutes. Hardly enough time to circulate blood to the bone marrow.
Just enough time, it turns out.
I was thinking the same thing. Seems rather sketchy.
