Be honest, kids just don't want to have the oldest parent on the school yard. Also, when you have kids later they are unlikely to have the joy of grandparents.
I would say early 30s is a sweet spot for having kids.
When I was a child I was proud to have a mum who was a bit younger than my friend's mums. Now it seems a strange thing to be proud of but I the time I was! I'm now 33 and keep mentally pushing back the age I'd like to have kids by. Now I'm thinking 40 is my limit. This may change as I approach 40! I hope my (imaginary potential) children won't mind having older parents. Possibly I was only proud of my young mum because she was young, and had she been older I'd never have thought about it!
I do my lon runs at more like 11 min/mile pace (a hang up frm marathon training days when I was going for a 4:30 mara). Possibly as going a bit slow but have managed just under 2:02 for a half this year.
I went for a 45 min run, the sun came out as I started, and I had good encounters with people. The young guy with a vicious looking dog, who shortened its lead as I approached and kept the dog to the side. The woman stood on the path who smiled and stepped out my way as I approached, even though it wouldn't have inconvenienced me to run round her. The man on the narrow path, surrounded by stinging nettles, who moved aside so I could pass. The couple leading two ponies on the same path who smiled and were thankful that I stopped to let them pass. And finally the women trimming their hedge, who stopped as I approached so I wouldn't get covered in little bits of leaf. I often read on here about people meeting selfish twunts on their runs, so was good to have lots of good encounters!
Traffic lights that take ages to go green for pedestrians
People who see you running towards them and make no effort to move over.
Car drivers who don't indicate
When a bus gets to the bus stop at the same time as me and a load of people get off slowly and block the pavement, I don't blame them, they're getting off the bus and not thinking about runners, but it is annoying!
Once as a pedestrian I was nearly hit by a drunk driver (they managed to hit a car parked half on the pavement, on a straight bit of road, and flipped their van on it's side!) My boyfriend is convinced if the car hadn't been parked there the van would have hit us and killed us. I think if the car hadn't been parked there the accident wouldn't have happened at all! As it is I ended up showered in glass and a small cut on my little toe!
