Be Aware Twitter Tracks Users

Initially it was confusing to read and write posts on twitter. Many left as they couldn't know whom to follow. Twitter with its suggested user list knew who followed whom. Then publishers placed Twitter buttons on websites to share pages.

Though you don't tweet or don’t have an account—the buttons tracks your data 

(deleted after ten days and not taken from European visitors, due to local laws) on 

website visit, if the publisher or you hasn't opted out. This is how Twitter gets users.

Face …the Book

As a user, have you ever been discouraged and turned away by the flood of information on Facebook? Hold on! No more irritation! In a way to address the issue and make its users happy, Facebook has made public a most important change to its home page.

It welcomes users when they log into the website. The Facebook News Feed with its latest design presents bigger links and photos and enables the users to see specific streams which are centered on topics like posts and music by friends.

3 Week Old Blood is not good for transfusion

As per a study blood older than three weeks may get spoiled and not be effective. After three weeks, the blood cells become more firm and so becomes difficult for it to enter the smaller capillaries. The cell membrane varies and the cell membrane that stiffens is prone to weaken the flow of blood through the smallest capillaries. It has been known for long that the blood gets damaged as it ages. The chemicals that help blood to deliver oxygen overturn themselves after a transfusion.
