Ever had a Spirometry Test

Well i learned something today. Relevant to us woodworkers. Yup a Spriometry test checks your lung capacity and air intake.

Something I guess thats worth doing annually to get an idea of whether your hobby is having an effect on your lungs and whether you got your dust under control.

Anyone had experience with one of these tests?

everybody need this test after they turn 21

They do it routinely in hospitals. The test is covered by insurance so everyone who is admitted has to blow the blue balls twice a day. Money maker for the hospitals.

I have COPD gotta do it every Dr. visit.
