I wroteYou can train for both, but Aregawi's a specialist and doesn't have 800 meter fitness
so were snell/ryun/coe/ovett/cram/asbel/baala/masterkova/holmes all figments of our imagination ???

Nothing in your rant disputes what I wrote about energy systems, which convinces me you really know nothing about it. All you seem to know is how to cherry-pick favorable statistics.
