No one can travel your own road for you; you must travel it for yourself.
I strive to be a skeptic, in the best sense of that word: I question everything, and yet I’m open to everything. And I don’t have immovable beliefs. My values shift and grow with my experiences—and as my context changes, so does what I believe.
No one can tell you how you must understand the world, and you can’t say what someone else must do or be.
“On any given day, the average American teenager spends more than 7.5 hours online and uses his or her cellphone 60 times. While these numbers strike fear in the hearts of parents and crotchety novelists lamenting the loss of a more meaningful existence, there are some real benefits to a technology-saturated life: Young people spend far more time consuming new information, honing verbal concision, and interacting with a diverse audience than they have at any point in history.”—Find out how youtube and facebook are changing our lives. | The Week (via 0riginal)
“Everything is as it is. It
has no name other than the
name we give it. It is we
who call it something; we
give it a value. We say this
thing is good or it’s bad, but
in itself, the thing is only as
it is. It’s not absolute; it’s
just as it is. People are just
as they are.”—Ajahn Sumedho (via thetaooflife)
Exercise triggers the creation of highly excitable neurons in the hippocampus, the region of the brain associated with memory, learning, and emotional responses. This speeds up overall brain function, but because of the new neurons’ excitability, it should also make the brain more susceptible to anxiety. Yet it doesn’t.
To find out why, the Princeton team split lab mice into two groups. One group had access to a running wheel (with the mice averaging an impressive 2.5 miles per night), and the other did not. After six weeks, the researchers intentionally freaked out all the mice by dunking them in cold water, then looked at their brains with an fMRI machine. Almost immediately, they noticed that the two groups reacted differently. The brain cells of the inactive mice became agitated and leaped into a frenzy, while those of the active mice did not. The reason: the active mice were able to produce and release more of the neurotransmitter GABA, which helps sedate jumpy neurons.
The discovery … marked a breakthrough in understanding how exercise helps the brain regulate anxiety. In essence, exercise creates new, faster neurons, but it also reinforces the physiological mechanism that prevents those uppity brain cells from firing during times of stress.
