I do simply because I look at the health properties of the tea FIRST and FOREMOST, flavour aroma and all that jazz comes second in my list.
In theory the healthiest teas would likely be powdered such as Matcha, as only so much of the leaf can be extracted, but when consuming the whole leaf you will get the most from the leaf. Although you likely won't make friends on this forum by claiming that all you care about from tea is its Health properties.
I am sure many of us on this forum would highly consider becoming criminals should Tea suddenly be outlawed. I am sure most would also drink it if it were shown to have damaging effects to the health effects similar to alcohol, or cigarettes.
Again I can not speak for everyone, but from the people I tend to talk to, the consumption of tea is a love affair for us.
