As a fellow tea drinker, I suspect the British would be appalled by my day to day tea-making and drinking method. I boil water, pour it over a teabag into a mug, walk away, and hope that by the next time I notice it, it's down to a reasonable drinking temperature, at which point I remove the teabag.
I'll grant that if I'm making good loose leaf tea, I'm pretty attentive to recommended brewing times, etc, but that's more of a weekend leisure tea exercise.
As an aside, I'm pretty incensed that my new electric kettle overshoots its set temperature and only holds temperature for 30 minutes. I'm semi-seriously considering trying to dump the firmware and improve it.
No, I'm not brewing tea with it. I'm keeping hide glue warm. I dropped my old "glue pot" the other day and needed a replacement now, not tomorrow.
