|
| It's hard to phrase because obviously the claim isn't they
| understand what it is etc.

| Certainly if it's beating fast I notice much more than resting.
|
| I think at rest I tend to notice it indirectly, particularly
| how it makes my body move or noticing it alongside a deep
| breath.

| If for some reason verifying it would actually impact your
| life, try to find definite proof for it, but otherwise this
| type of thinking is generally detrimental as you end up with
| snowflake syndrome and will ignore meaningful statistics or
| advice as "not applicable to you" when in all likelihood
| you're just like everyone else.

| I think you misread me.
|
| "some times more than others" means "more than other
| times", not "more than other people". Meaning that there
| are times I'm more sensitive to it than other times. It's a
| sensation that fades into the background most of the time.
|
| It would be totally insane for me to assume I'm especially
| good at it.

| Must be fun coming up with ways to test ideas like this:

| > We first got our monkeys to sit in chairs in front of a
| computer screen and hooked them up to electrocardiograms to
| monitor their heartbeats. Then we played videos of either a
| yellow or green cloud bouncing up and down accompanied by beeping
| sounds. Sometimes we would sync the bouncing and beeping to match
| the monkey's heartbeat, and at other times they were out of sync.
|
| > We then used eye trackers to measure how long the monkeys
| looked at the images. If the monkeys had a sense of their own
| heartbeats, they would find the in-sync bouncing less interesting
| and novel than the out-of-sync bouncing and so would spend more
| time looking at the out-of-sync image.
|
| I wonder if you could get them to tap along or similar to a
| sensor that was beeping to their heart beat where you made the
| beep quieter and quieter until eventually silent.

| Which monkeys? If they are ones that can already pass the mirror
| test, this doesn't seem like anything astonishing.
