Is alkaline water better for your body?

My friend recently bought a water filter. It's purpose is to raise the tap water's pH-level to alkaline level. She claims that alkaline water is good for our bodies because it reduces the acid level in our bodies. Is it true that waters with high alkaline (pH) level are really healthy for the human body? She paid $1000 for this water filter. Is it worth it? Please let me know soon if it's actually good for me, I'm thinking of purchasing one.


How can I grow and strengthen my nails?

My fingernails fray and chip all the time. I have tried many different nail polishes and nail hardener but nothing helps. I've been trying to grow my nails for the past year and I just can't seem to get them to grow. My mother and older sister don't have any problems getting their nails to grow. Please give me some tips on how to make my nails grow stronger and fast.
