Is having grey hair at 32 years old normal. my wife is 40 n has none. does this indicate my poor health since grey is sign of ageing n i'll die early?

Don't be silly: This is a benign genetic trait. Nothing more.

Don't worry about : dying early due to gray hair. Reasons to gray early.1.Genetics. 2. Age 3. Stressors. The age of initial graying is largely due to genetics. Stressors like nutritional deficiencies, traumatic head injuries, low Vit. B levels, zinc deficiency, severe illness, surgery & marked emotional stress may cause earlier depigmentation in people who are predisposed to gray hair. Genetics is major factor.
