There is a "line" your body would know you cross that line by giving you warnings such as feeling stuffy, headache, nausea, volmit, etc My point is, dont ignore such warnings and press on, should that happen.

If you have heart and blood pressure issues in your medical history, you better think twice for high altitude adventures.

10,000ft is nothing for most folks if they dont have to exert themselves.
