How much do you avail yourself of your nearest VA?

Chalk up another zero-usage.
As long as I can afford to pay for my own medical care, I'll decline using other people's money. Having to actually pay for something forces me to decide what is (or isn't) worth spending the money. I've noticed (especially in the medical field) that people are much less likely to ask if it's worth it when they don't see the price tag before they decide.

None

Zero! When I retired 27 years ago, I was had to attend a retirement seminar, and they informed me that even though I would get a retirement dental and medical physical, I should check in with the VA for another physical. I did that, and they gave me a physical, and told me I had no service disabilities and was shown the door. I never went back.
