Have you?¿Have your blood tested without then again with a respirator.
Bet most that say they never use anything or say there is no need
have never had the levels in their blood checked.

Well, in my case you'd be wrong. The last test was in August, it was 7.0. Considering how much I cast, load lead boolits, tumble brass, and shoot, that's not bad at all. For adults anything under 40 is not to worry about.
