My hair started graying pretty much as soon as I graduated from college. It makes a lot of sense now. Around the same time, I:<p>- bought a house (in 2007, yeesh)<p>- got married<p>- started my first job (which at the time felt like drinking out of a fire hose)<p>Shortly after, my wife and I went through the stress of trying and failing to get pregnant. Then infertility treatments for several months. Then my wife had surgery. Infertility treatments no longer an option, we turned to adoption. 6 weeks later (seriously), we brought home our first child.<p>After that, it was like kids fell into our laps every couple of years. After the second child, I struggled with a pretty severe addiction that nearly claimed my marriage. Since then we've adopted two more. We now have kids aged 12, 9, 6 and 4.<p>Has it been all stress all the time? Not at all. I feel incredibly blessed to be living this life. But the hair (mostly on the sides) hasn't gone back to its normal color either, so I guess either it's genetic or there's an undercurrent of stress I've just become accustomed to.<p>Edit: formatting
