a quick apology and a question

[Alex88]

first of all a quick excuse to those who care about this forum and wasted time to read my painfully negative last topic here. It was a bad week and i pretty much succumbed in spitting my own negativity(due to stress and family related issues,to say the truth) in a forum - stupid move. So again,sorry to everyone involved.

Maybe this is no news to anyone as a request,and i'm pretty sure there's another thread somewhere (in which case if you can post a link,i'd be grateful) about this topic - but its here a way to calculate the best density without doing childish things or being screwed by some doctor? i mean,aside of having a hair counter?

thanks
