Getting old?!

I went to "拜山" yesterday and all my body are so sore as expected (especially my legs and my hips) >.<

I used to take an hour and without any stopovers to get there when I was a kid. But it took me nearly 2 hours and with millions of stop overs to reach there yesterday. Gosh, am I getting old or just because I didn't do any sports for long time? Maybe it's time for me to grab my golf bag & get myself in sweat!
