In any case, there is nonetheless a good deal of evidence to indicate that modafinil is producing at least a portion of its wakefulness-promoting effects by acting as a DRI, or at least via activation of the dopaminergic system. In support of modafinil acting as a dopaminergic agent, its wakefulness-promoting effects are abolished in DAT knockout mice (although it is important to note that DAT knockout mice show D 1 and D 2 receptor and norepinephrine compensatory abnormalities, which might confound this finding), reduced by both D 1 and D 2 receptor antagonists (although conflicting reports exist), [64] and completely blocked by simultaneous inactivation of both D 1 and D 2 receptors. [57] In accordance, modafinil shows full stimulus generalization to other DAT inhibitors including cocaine, methylphenidate, and vanoxerine, and discrimination is blocked by administration of both ecopipam (SCH-39166), a D 1 receptor antagonist, and haloperidol , a D 2 receptor antagonist. [61] Partial substitution was seen with the DRA dextroamphetamine and the D 2 receptor agonist PNU-91356A , as well as with nicotine (which indirectly elevates dopamine levels through activation of nicotinic acetylcholine receptors ).

“Having an extremely low body-fat percentage can affect the cardiovascular system’s ability to function normally,” says cardiologist Kevin Campbell , ., fellow of the American College of Cardiology. For example, in one study published in the International Journal of Sports Physiology and Performance , when bodybuilders prepared for competition by lowering their body fat, their heart rate dropped to 27 beats per minute. Too low heart rates, called bradycardia, can lead to dizziness, passing out, and cardiac arrest. Meanwhile, other electrolyte imbalances due to too-low of a body fat percentage, not to mention caloric intake, can lead to “cardiac arrhythmias and sudden cardiac death, he says.

The write up/article definitely makes a point. However, as a student of New Communication Technology, I feel Technology has helped and improved communication immensely in more ways than it’s mentioned in the article. The key importance of communication is proper dissemination of information or news and this has been achievable by the New Communication Technologies. More so, it has helped to strengthen inter-personal communication through chat applications and social media. Through these websites, there’s need for constant and effortless contact with people you know and even new people.
Another advantage is the easy access to information via the Internet. Reporters today even source their articles from the internet. As a matter of fact, you did use a gadget of technology to share this information, didn’t you?
You cannot blame technology for the reasons you have mentioned. You blame what people are doing with technology.
