HAIRCUTS DON'T HURT


HAIR CUTS  DON'T  HURT.The   reason  is  quite  simple, because    hairs   are  made   of  dead  cells,so  we  don't  feel  pain.The  dead  hair  cells  are  filled  with   a  tough  ,    waterproof  protein  called  Keratin,  as are  nails,   and  the  skin  flakes  that  we   lose  daily  in  their  millions  from our  skin  surface.All  these  things    are  part  of  the   protective   overcoat  that  cover  and  protect   our  body.
SKIN-  Skin  is   really   thin  but  quite   complex .Its  made  of  two  layers ; The  epidermis     provide  protection, and  is  constantly worn  away and   replaced.The  dermis  glues  the   epidermis  to  the  rest  of  the  body   and  deals   with  feelings, temperature  control,  and  food  and  oxygen  supplies

SWEAT  GLAND.-  The   Armpit   sweat  glands  produce  a  thicker    sweat    than    the  body's other  sweat  glands..When   bacterias   feed   on  this  sweat  they  release   chemicals   that  can  smell  musky  and  unpleasant.

SKIN  DWELLERS- Many  kinds  of  organism   live   in   our  skin.Some  common  one's  are-
Fleas-  These   feed  on  blood   and  then  leap  on  to  the   next  victim.
Head   Lice- The  most  common  ,it   grip  hairs,lays   eggs  and  then    pierce   the  scalp  to  feed  on  blood.
Ticks-  It  attach   to  the  skin    and  blow  like  a  balloon,as  they  feed  on  blood  and  then  drops  off.
