My joints are creaking. On a 20 mile bike ride with my sister, my knees were aching. My back was aching. My neck was aching. I think the only thing that wasn't aching was my face. I hobbled off my bike, and said to my sister, "I'm getting too old for this!"
My lovely sister didn't say, "No, you're not." or "You're still young."
She tells me, "Hah. Some people don't even START triathlons until they're in their 40's or older!"
Yeah, that made me feel soooooo much better, knowing I'm going to be passed by 50 year olds. LOL
