erm my brother and girlfriend both have this
my brother on both of his hands have short life lines, tat day he casually asked short life line is it mean tat i will die young
i sort of brush his comment aside , but it still bothers me though.........

for my gf i think on her lefthand, she had a broken lifeline, the line starts out and then broke at roughly half of its length and then after the brake, a second line continues
she too ask me the same qn, it still bothers me though, we rarely talk abt it
