getting back my reading mojo
delving into books
I never thought I'd enjoy
or get past the first few pages

or even understand

but this book 
I can't put down

carbon-14 is in all living things

when living things die

they stop taking in carbon-14 

and so the radioactive clock is reset

reliable detective work for carbon dating

if the thing is less than 60 000 years old

we all know about counting tree rings 

it's called

dendrochronology

each ring a year of growth 

tell tale by it's size

changes in climate, weather, illness

trees keep growing until the die

the creationists debunk
the conspiracists conspire

instead of convincing us it's not true

maybe show us how it is?
