there's really nothing to worry about.
when i was five or so, my classmate accidentally poked a pencil
into the palm of my hand, after which blood came oozing out. when i
got home, my mum got so worried, she tried ways and means to get
that piece of lead out of my palm. she told me that if the pencil
lead was not out, it would get into my heart and i may just die. so
i cinched as she pierced a needle through my skin in a futile
attempt to get the lead out. the pencil lead however, did not
budge. i tot i was REALLY going to die then. but more than a decade
has passed, and i am still alive.
