Life is not worth living without love ones to protect, something you could never begin to understand.
Shinobi use sand for numerous supplementary functions ranging from concealment to disguises and attacks.
Sand is a strong element to wield due to its proficiency for both attacks and defense. Lighter minerals and finer sand make for quick attacks, where as heavy more dense sand make for strong defensive means. Though sand is subjectable to many weaknesses. Sand can be countered by mixing other substances into it such as, explosive clay which potentially harms the user, Gold dust makes the sand heavier and slower, or oil, which makes the sand crumbles very easily.
Sand differs from other elements as I can not just create it through chakra alone, tho I can make more by using sand already being manipulated by my chakra to grind down earth elements around me.
