arms	are	serving	as	the	shield	to	the	torso,	and	the	hands	are	given something	to	do. 				 Crossing	one's	arms	can	also	be	seen	as	an	attempt	to	block	the	torso. A	pose	that	is	more	common	in	women	is	holding	an	elbow	with	the opposite	hand. 	(See	below	for	more	explanation. ) 				 Carrying	books,	bag,	or	purse	in	front	of	the	chest	can	signify nervousness. 	Imagine	someone	on	their	way	to	an	exam,	and	holding their	books	to	their	chest. 	 If	someone	is	complaining	about	the	cold	and	no	one	else	seems	to	be	affected, perhaps	this	person	has	a	reason	to	feel	uncomfortable. 	When	the	body	feels under	threat,	the	limbic	system	actually	transfers	blood	from	the	skin	to	the muscles	as	in	preparation	for	fleeing	or	fighting,	which	makes	the	skin	cooler. Sometimes	they	will	appear	paler. 	 	 ARMS	&	HANDS 	 Exposed	necks	and	palms/insides	of	wrists	are	signs	of	trust	and	openness. 	 Sweaty	hands	may	be	indicative	of	anxiety,	nervousness,	or	fear. 	People	with sweaty	hands	may	tend	to	rub	their	hands	on	their	pants	or	clothing	in	an	attempt to	dry	them	off	(although	rubbing	of	the	legs	itself	can	be	a	general	stress reliever/pacifying	behavior,	with	or	without	the	sweaty	palms). 	This	act	also tends	to	cause	small	clothing	fibers	to	stick	to	their	hands	due	to	the	moisture, which	may	be	observed. 	 A	firm	handshake	can	indicate	a	person	who	is	more	extraverted	and	less neurotic 	(as	in,	less	emotionally	stable,	less	confident,	and	more	worrisome). 	A firm	handshake	may	also	indicate	openness	(as	in,	to	new	experiences)	in women. 	 A	weak	handshake	can	indicate	one	who	is	introverted,	neurotic,	and unexpressive. 	 	 LEGS	&	FEET
