I'm not sure what the answer is. I'm fitter and healthier now compared to 3-4 years ago. All my friends are getting fat, but I went the opposite way, I lost weight.
When I look at old pictures, I feel proud of myself that I lost more than 20kg. However, I also realise I'm getting old. I don't really care about my hair anymore, I think hair is a representation of getting old and that's why I had issues with my receding hairline.
Oh well.. It's not so bad, I feel young at heart. Besides, I'm only 30 and I have a few more years to mess about.
