[extropy-chat] Nanoparticles linked to chronic lung diseases

[Lifespan Pharma Inc.]

Oh, Oh.....Just what I wanted to know....... I'm a walking test rabbit 
for the processes you mention.
For 3 years I operated a farm tractor with a cracked manifold and I am 
sure sucked in several hundred hours of
that sweetish smelling nano-puke a diesel engine puts out.

What concerns me is the residual nano particles that might become  
incorporated into lung tissue
and continue to generate "silent inflammation" over a lifetime.
