Vasovagal reflex
A lot has been going on. My father-in-law had a silent heart attack and had to undergo quadruple heart bypass surgery on 18 July. We are all well acquainted with Mt Elizabeth Critical Care Unit & Ward 6.....and Coffee Bean & Tea Leaf. It was good when he was discharged and is recuperating slowly but surely next door. The Pince family (cousins from Laguna Hills, California) have been in town visiting. Last weekend, we had a short getaway at the Changi Village Hotel.
Last Saturday, we all went to Pulau Ubin to check out the Ketam Mountain Bike trail. This was Tim's 3rd time but my first. It goes around the quarry and if supposed to be of race championship standard - pretty technical. Well, I was concerned for the safety of all the boys as we tackled this course. I off-road much more often than they do and wasn't sure how they'd handle it.
It's really fun. Quite narrow and single track all the way with plenty of hair-pin turns. It was middle of the day hot but we were shaded in the jungle. Anyway, merrily going up and down and sliding along I somehow managed to scratch up my legs. And then.....scrape a chunk of skin off behind the knee on my right leg. It looks raw and I feel the pain....a bit of bleeding. There is no plaster big enough.
We are a big group of 8 and so stop to re-group every now and then. I feel the pain behind my knee and then we suddenly stop to re-group. In a second, my head feels faint...I ask if anyone has a plaster but realize I can't say much else after that. I think I'm off my bike and I lean my hand on the tree to steady myself. Before I know it, I hear Keith warning whoever to grab hold of me because I'm about to faint. True enough, I'm unable to stand any more and am helped to the ground. Slowly I feel blood coming back to my head and things get clearer.
I had a vasovagal reflex most likely triggered by my cut.

The vasovagal reflex, which causes the heart rate to slow and the blood vessels to widen, or dilate.
As a result, blood pools in the lower body and less blood goes to the brain. This reflex can be triggered by many things, including stress, pain, fear, coughing, holding your breath, and urinating.

We are more than halfway through Ketam trail and I'm wondering how I'm going to finish it properly. Fortunately, there is a parallel road (Jalan Wat Siam) where I can exit and head to NParks office to get first aid. Bummer...but that's life.

Fully recovered after having my wound bandaged up & a hearty seafood lunch, we head out to Chek Jawa on the eastern side of Ubin. Photos at the old colonial house and a quick coastal boardwalk trek....black clouds loom everywhere. We see lightning activity and wonder why so many silly people have climbed up the lookout tower. Cycle furiously back to jetty and almost make it....except for the last 200m where we all get absolutely drenched.

Fun. Very fun.
