quick but short

[Guest guest]

as an experiment, scientists put rats under

 

markedly refrigerated temperatures.

 

 

 

the rats adopted by speeding up their metabolisms:

 

remaining particularly active

 

to keep warm

 

 

 

surprisingly, to the scientists,

 

the rats survived.

 

 

 

and procreated

 

for several life cycles.

 

 

 

but their life span

 

was significantly reduced.
