acute angle, doubleplus-uncute pissed-off human, acute pain.
why? i highsided my bicycle just an hour ago: i chose too acute an angle when passing from the grass onto a concrete pathway, the grass was high and hid the large difference in height, the front tire caught and stayed down on the grass and i got tossed over the frame and deposited onto the concrete.
one big bruise on my hip, a skinned knee and forearm/elbow. not too bad but still annoying. the second half of my usual 26km round was not exactly comfortable - but i did not shorten the distance.
