💅 Why do we have toenails and fingernails?

Nails are like tiny shields for your fingers and toes! 🛡️ They help protect the soft skin underneath when you touch things or bump your toes.

Nails also help you pick up small things, like toys or food. �

Nails are made of a tough protein called keratin, just like your hair! 💇‍♂️ They protect your fingertips and toes from injuries.

Nails also help you grip things better, like when you peel a banana or open a can. 🍌

Plus, they act like tiny tools—scratching an itch or removing a sticker! ✂️

Nails are evolutionary tools made of keratin, a protein that also forms hair and animal claws. 🧬 They serve multiple purposes:

• Protection: Shield fingertips and toes from trauma.
• Enhanced grip: Help with precise tasks like buttoning clothes or using tools.
• Sensory feedback: Nails press against objects, improving touch sensitivity.

Historically, nails were crucial for survival—scratching, digging, or self-defense. Even today, doctors check nails for health clues! 🩺
