Calm.com's maximum, 20 minutes is quite a short meditation.
It takes me about 35 mins for a chance at losing my self in space and getting out of my skull (when the brain really starts doing noticeably interesting stuff).<p>@zenbowman @tucosan
I mostly meditate alone on my computer chair and it can work totally fine, I have many friends that do the same every day.
I would get rid of the 2 mins, and add 30,40,60,120 mins. If needed, fold out on hover.<p>Sure our devices can be noisey, but just like when sleeping, people can stop the noises.<p>Physical exercise is a great idea, and goes well with meditation. Also there online communities for meditation and practice these days, which is a good way to build reinforcement as we're social creatures.
