sight sound touch taste smell

The body has 5 main senses:






sensors in the middle ear detect the head's position and movements while those in muscles and joints bring information about the poition of the body and limbs.

Which helps us to keep our balance

Other micro sensors detect internal body conditons such as temperature and blood pressure.

Smells are scent molecules taken into the nose when we breathe

Something like a lock and key, when a particle fits properly ,only then is a nerve signal sent to the brain.

Taste relies on sensors in the tongue, "the taste buds are on the top of the tongue" as the saying goes.

The tip of the tongue is sensitive to sweet tastes, the front sides to salty, the rear sides to sour, the middle rear to bitter

The sense of touch relies on sensors in the skin, including light touch and heavy pressure, heat and cold, movements and vibrations.

In the fingertips there are 10,000 microsensors in every square millimetre of the skin.

Sight is more difficult and we'll cover that another day.

And some on hearing, too as opposed to balance explained in this post.


What computer systems are supported?

News from Lumosity

The following list shows which systems we have tested Lumosity on and can guarantee performance with. The largest impacting factors for site performance are your browser (what you use to access online content), your operating system (how your computer runs and stores files, programs, etc), and your Flash Player (a browser extension built by Adobe that allows interactive content such as games to run).

Because computer technologies rapidly change, we are not able to guarantee that Lumosity will function flawlessly on all systems. Newer technologies tend offer better experiences, so we try to stay up-to-date with the newest versions of each system, and older versions will eventually become unsupported. To optimize your web experience, we strongly recommend using the latest versions of browsers and Flash Players available for your operating system.

If you are not sure what browser, operating system, or Flash Player you have, visit Information about your browser and computer will be automatically detected and reported to you.

We support the following browsers, operating systems and Flash Players:

Supported Operating Systems
•Windows: XP, Vista, 7 and 8
•Mac: Tiger, Leopard, Snow Leopard, Lion, Mountain Lion, and Mavericks (or OSX 10.4 )
* At this time, Linux is not supported. Since Adobe has stopped releasing Flash updates after 11.2, we recommend that Linux users access Lumosity using Chromium, which has a Pepper Flash that is up to date. In addition, Linux users may encounter some strange behavior in our games, including but not limited to incorrect key mapping. We hope to completely support this operating system in the future. If you experience any game issues in Linux, we recommend switching to a different operating system if possible.

* At this time, Linux is not supported as Adobe has stopped releasing Flash updates for this operating system. Linux users may encounter some strange behavior in our games, including but not limited to incorrect key mapping. For best results, we recommend that Linux users access Lumosity using Chromium, which comes with its own version of Flash that is up to date.

Supported Browsers
•Firefox 12.0 (Windows, Mac)
•Chrome 20.0 (Windows, Mac)
•Safari 5.0 (Mac)
•Internet Explorer 9.0 (Windows)
Supported Flash Players
•Flash 10.1


Beware These Fatty Acids

Improve Your Cholesterol


Monitoring LDL and HDL cholesterol is smart, but don't overlook your triglycerides.

When it comes to cholesterol, HDL (good) cholesterol and LDL (bad) cholesterol aren't the only numbers to watch. Your doctor will screen your triglyceridestoo.

Triglycerides are fatty acids that act as the basic building blocks of fats. Your body converts the excess calories you eat into triglycerides, which are stored in fat cells. As needed, hormones regulate the release of triglycerides from fat tissue to meet your body's energy needs.

In terms of cardiovascular disease prevention, triglycerides haven't not gotten as much attention as LDL and HDL cholesterol, but research has shown that high triglyceride levels of 200 mg/dL or more (hypertriglyceridemia) can increase your risk of cardiovascular disease.

How can you keep your triglyceride levels down? A heart-healthy diet that's low in saturated fats can help tame high triglycerides. So can exercise.
