Really, that proves why blood underground or anywhere not under rain / wind stay forever without being degraded... And even better resist in oxygen rich environment to cold - hot cycle. Like under a porch.
MOS, where should i start laughing ? Blood left drying under a unprotected place will degrade with time, for many different reason non bleach related (bacterial attack for example). In a really protected place, like a home inside the fiber of a carpet, it can stays for years, but even there it will degrade to the point that part of the DNA will not be readable anymore. As a rule all biological material sooner or later degrade (and blood is not that rich in DNA anyway to start with, IIRC my biology us mammalian don't have DNA in our red cell). But on a NAIL outside, through winter and summer name me Thomas the doubter. And even if I was giving you in that some blood was left, it does not explain why a mega-special-uper-duper new method was needed to show blood presence, methoid which by the way was not peer reviewed.
Sorry, I'm the one laughing. You guys crack me up.
