What if lowbloods live shorter because of Glubglub's influence? If she goes louder than a wisper, trolls start dying, but we don't know if there are any OTHER side-effects on living beings that are more psiionic-sensetive, such as decrease in life span! Just a small headcanon of mine

The Lifespan thing also happens in Beforus, it seems to just be Troll Genetics.
