TRY SAYING POLYDACTYLY TWICE
 
 
�            If you think you’re a zom­bie, then there’s a good chance you have
Cotard’s delu­sion. The men­tal dis­ease makes the afflict­ed think
they’re dead, or undead. They often pass away due to a lack of food
and water as they don’t think they need to eat as they are already
dead.
 
�            Urticaria is a sci­en­tif­ic term for a type of hive or skin rash. Most
urticarias are caused by aller­gies.
 
�       Fre­goli delu­sion is a rare psy­cho­log­i­cal dis­or­der where those afflict­ed
with it believe they keep see­ing the same per­son in dif­fer­ent places.
For exam­ple, a Fre­goli suf­fer­er may see his father’s face on peo­ple
who are clear­ly not his father.
 
�            Peo­ple who expe­ri­ence pan­ic attacks often think they’re going to
faint, but blood pres­sure rais­es dur­ing a pan­ic attack, while faint­ing is
usu­al­ly caused by a sud­den drop in blood pres­sure.
 
�            Poly­dacty­ly is a con­di­tion where a per­son is born with extra toes or
fin­gers. For­mer Mex­i­can Pres­i­dent Vicente Fox has poly­dactylism,
with six toes on each foot.
 
�            Necro­tiz­ing fasci­itis is a bac­te­r­i­al infec­tion that kills a body’s skin
and oth­er soft tis­sues. It usu­al­ly hap­pens after a wound becomes
infect­ed and is then left untreat­ed.
 
�       A per­son who breaks out in hives from con­tact with water prob­a­bly
has aqua­genic urticaria. A per­son with this afflic­tion can drink water,
but any exter­nal con­tact cre­ates hives.
 
�            Up to 20% of the Amer­i­can pop­u­la­tion may be aller­gic to the
chem­i­cal nick­el. This could be big con­sid­er­ing that nick­el is a major
com­po­nent in smart­phones.
 
�            The fear of long words is known as
hip­popo­tomon­stros­esquipedalio­pho­bia . I don’t see how that long
name helps those with this pho­bia, do you?
 
�            Have you ever heard a gun­shot as you were about to fall asleep? If
so, you may have expe­ri­enced explod­ing head syn­drome (EHS).
 
�       No pain no gain? Not if you suf­fer from con­gen­i­tal anal­ge­sia. Those
with this rare genet­ic con­di­tion sense none or very lit­tle pain.
 
�            If your urine has sud­den­ly turned pur­ple, you may have por­phyr­ia.
Por­phyr­ia is a rare liv­er dis­or­der that caus­es tox­ins called por­phyrins
to accu­mu­late in the body.
 
�       Prog­e­ria is a genet­ic dis­ease that caus­es chil­dren to age sev­en times
faster than nor­mal. Chil­dren with prog­e­ria lose all their body fat and
their hair, devel­op wrin­kles, and usu­al­ly die in their teens.
 
�            From 1941 to 2009, there were 62 record­ed cas­es of for­eign accent
syn­drome. A per­son with this con­di­tion begins speak­ing in a for­eign
accent, usu­al­ly after a trau­mat­ic head injury.
 
�            If you’ve noticed that your girl­friend smells a lit­tle fishy, she may
have trimethy­lamin­uria. This hap­pens when a person’s body stores
too much trimethy­lamine, caus­ing a fishy odor.
 
�            Your con­stant­ly out of work broth­er-in-law may not be lazy. He
could just be suf­fer­ing from ergo­pho­bia or the fear of work!
 
�            About 1.3% of the pop­u­la­tion will expe­ri­ence pityr­i­a­sis rosea at
some point in their lives. It cre­ates a rash over the tor­so, arms, and
legs that last for up to three months. The caus­es of her­pes relat­ed
virus­es are unknown.
 
�            Alaskans, Cana­di­ans, Rus­sians, and Min­nesotans may love win­ter,
but for some it’s dead­ly. Peo­ple with cold urticaria can die if they are
exposed to cold air for too long.
 
�       In rare cas­es, insom­nia can be fatal. Fatal famil­ial insom­nia begins as
a nor­mal case of insom­nia but quick­ly pro­gress­es to demen­tia and
then death.
 
�            If you feel the urge to eat dirt, paint, or even feces, then you may
have pica. Pica is the urge to eat uneat­able things and although rare
over­all, 28–68% of all preg­nant women expe­ri­ence it.
 
�       Noma is a rare infec­tion of the mouth and face that’s found pri­mar­i­ly
in the devel­op­ing world. It’s caused by poor san­i­ta­tion, hygiene, and
diet.
 
�       The next time you think about putting glit­ter on before a date, make
sure he or she isn’t aller­gic to mica. Most glit­ter is made from mica,
which is also an aller­gen to some peo­ple.
