Scientists have revealed a simple trick for boosting your memory.
Reading something out loud is the most effective way of retaining information, a study found.
This is thought to be due to both speaking and hearing words making them more personal and therefore increasing the chance they will stick in your mind, the research adds.
Lead author Professor Colin MacLeod from the University of Waterloo in Ontario, said: 'This study confirms that learning and memory benefit from active involvement.
Dengvaxia, a dengue vaccine available here since March, could prove harmful to people who have never been infected by dengue.
Sanofi Pasteur, which produces the vaccine, sent out an alert saying: "For those not previously infected by dengue virus, the analysis found that in the longer term, more cases of severe disease could occur following vaccination upon a subsequent dengue infection."
However, for those who had been previously infected, it "provides persistent benefit against dengue fever".
Dengvaxia, the world's first dengue vaccine, was approved by HSA last year for use among patients aged between 12 and 45.
A Florida hospital faced an unsettling ethical quandary when paramedics brought in an unconscious patient with "Do Not Resuscitate" tattooed across his chest - leaving doctors grappling with whether the message accurately conveyed his end-of-life wishes.
Doctors meanwhile gave the man basic care to buy time while they considered the life-or-death choice.
Doctors opted to follow that advice and the man died during the nigh after following their consultants' advice.
Social workers eventually found a copy of the man's "out-of-hospital" DNR order from the southern US state's health department - and doctors were "relieved" that it was consistent with the tattoo.
Lesson to be learnt here:
Tattoo is not only for the trendy. It can be used as a powerful tool to convey personal message.
Other useful usages of tattoos include names on babies or twins to distinguish them, contact numbers or address (in case of senile), last wish (no autopsy, no cremation, etc).
