A	person	who	smiles	with	all	of	their	(straight)	teeth	and	much	of	their	upper gum	visible	is	likely	to	have	had	braces. 	 	 HANDS 	 Look	for	scratches,	scabs,	or	scars	on	a	person's	hands. 	Their	dominant	hand will	likely	have	more	imperfections	than	their	non-dominant	hand,	because	their dominant	hand	is	often	subjected	to	more	precarious	situations. 	 A	left	handed	person	may	appear	to	be	ambidextrous,	but	that	is	because	they were	brought	up	in	a	society	that	is	tailored	to	right-handed	people,	so	they	have adapted	and	may	do	some	activities	with	their	right	hand	or	foot,	such	as	kicking or	throwing	a	ball. 	 Scientifically,	if	a	person's	ring	finger	is	longer	than	their	index	finger,	they have	more	testosterone	than	estrogen;	if	the	index	finger	is	longer,	they	have more	estrogen	than	testosterone. 	What	this	translates	to:	for	a	woman,	having more	testosterone	lends	itself	to	homosexuality,	and	more	masculine	or	 “boyish” qualities. 	For	a	man,	having	more	estrogen	lends	itself	to	homosexuality	or	more feminine	qualities. 	This	should	certainly	be	taken	with	a	grain	of	salt. 	Please	do not	automatically	assume	that	the	person	is	homosexual,	as	that	can	be	a	tragic and	rather	offensive	mistake	to	make. 	 If	a	right-handed	smoker	often	smokes	with	their	left	hand,	it	may	be	because they	drive	often. 	They	smoke	while	they	drive,	and	flick	the	ashes	out	the window	easily. 	(This	of	course	does	not	apply	in	countries	where	the	driver's seat	is	on	the	right. )	This	is	not	the	only	plausible	explanation,	however,	as	they may	just	be	a	multi-tasker. 	 	 TAN	LINES
