Aging is in the genes. Depends on the genes you inherit. She probably has bad genes.
True enough. My mom's 54, and looks about her age. My dad is also 54 but looks about 45. I'm 28, and with a baseball cap on I can pass for 18, but without it I could say I'm 35 and people would also believe me with the shaved head/goatee look I am sporting.
