What do you mean? If you dont accept critics, you have not to change your life. I am not responsable for your life, neither you ruining yours. If you have a good blood pressure, everything is okay and there is no harm. I doubt you controll yours, because the most have an elevate blood pressure.

Beside the neurological effects etc.

There are some positive effects of caffeine, for example on TNF-a . But you can also just use garlic to block the TNF-a for example.

But I will stopp here and dont waste my time.
