    Losing your virginity

    You're barely old enough to be a rider according to our poll Even I don't feel so old, now that I saw this profile https://forum.electricunicycle.org/profile/6116-ken-bland/ . Now that's inspirational!

    I don't know if we can count your entry. Isn't there some minimum age before you're old enough to be allowed to vote?

    Annoying and dangerous to be sure. Even worse, however, are the trees and telephone poles that jump out of their holes in front of you and block your way...

    Falling off a stationary unicycle head first can be fatal. It obviously makes things worse if you're moving forward, but just the 2 meter drop is, by itself, very dangerous. When the wheel flies out from under you, you go into free fall. It's not the same thing as tripping while on a jogging run. There is no friction under your shoes like there is when running. So it doesn't matter if your EUC was moving forward at jogging speed or not. You may not get a chance to "run it out". You could be going flying without a plane or parachute. To Toshio's point, I agree practicing falls so that you instinctively protect your head, and impact first with your toes and arms, is an excellent idea. Never seen any videos of normal EUC riders doing that, however. I'll have to watch EUC Extreme's videos again to see how he falls, perhaps he's using that technique. Just know, if you impact the ground with your unprotected head before the rest of you catches up, it's gonna be bad, even if you were only moving at walking speed...

    In the news...

    My next survey should be about monagamy. As in how many of you are faithful to only one wheel, vs how many of you are polygamous and have multiple loves?

    It's one thing to stare down Dirty Harry's barrel. It's another to play Russian roulette. One thing is not under your control, it's a risk you can't avoid if you partake in the activity. The other is a deliberate choice. As a daily motor scooter rider on some of the most dangerous streets in the world, I am keenly aware that I take a small but non-trivial risk every time I go on the road. With the high heat and humidity here, I would much prefer not to wear a helmet. But I know better.

    Problems are, at low city cruising speeds, riding with raised arms is not practical, and it takes about .2 seconds for even a trained athlete to react. That leaves .4 seconds to raise your arms and straighten out. My cat can do that, most people won't even know they are in free fall until it's too late, as they're still hoping their feet will come down on the pedals. Starting martial arts training at 40 - 60 years of age is also not likely. Bottom line is it's far better to wear wrist guards and a helmet for every ride.

    Keeping your hands up at speed is a good tip, as is tucking your head to the side and tensing your neck muscles in a fall. Straightening your legs and sliding on your feet and forearms will leave a lot of your skin on the pavement if you aren't wearing pads, however. Like you said, that takes practice, since most people's reaction will be to raise their head, bend their knees and try to run it off if they have time to react at all. Another place to practice might be to fall (not dive) from the side of a swimming pool.

    If you're riding in traffic, the more likely cause of a crash will be the motorist who doesn't see you and cuts in front of you, or hits you broadside, or the pothole that causes you to lose it, not the guy who clips you by passing too close. Anyone who rides without a helmet in traffic in the hopes that he/she will be safer because they think cars will give them a wider berth is taking a grave (and I think foolish) risk. But that's just my opinion.

    Many good techniques for dealing with falls in different martial arts, but if you don't have any warning it's coming, it takes longer than .6 seconds to respond. You might have time to tuck your head and begin a body twist, but more than that?? Do you think you're good enough to take the test I proposed in the first post of this thread?

    I completely agree with what you say here, particularly the parts I highlighted in bold text. At 40 km/h, your body will contain 5 times as much energy to dissipate if you fall, than if you were stationary, if my math skills don't fail me. My point is, that I think you underestimate the danger of just falling from an otherwise stationary position. The terminal impact velocity if you land head first will be over 6 meters per second (20+ kph). That's more than enough to be fatal (see table below). Every kph of wheel velocity you add to that number increases the final impact speed. But you can only die once . You probably won't land head first, but you also know you could. Helmets are not a panacea for every contingency, but they do improve the odds. Riding without one is an unnecessary and completely avoidable risk. So for me, the absolute minimum riding protection would be a helmet and wrist guards. Even just learning to ride. Maybe especially just learning to ride ---------------- from http://www.internationalbrain.org/examination-of-bi-thresholds-in-terms-of-the-severity-of-head-motion-and-the-brain-stresses/ Table 2. Correlation of ICP and acceleration of the head with HIC scores Speed of impact (m/s) Acceleration (g) ICP (kPa) Shear stress (kPa) HIC 1 62.1 47.4 3.71 196.1 2 140.3 137.3 9.31 363.8 3 222.3 191.1 14.05 705.3 5 317.07 276.14 25.64 1939 A similar response and correlation can be seen in the behavior of brain tissue shear stress as depicted in Figure 2(c); At 1 m/s no injury is expected. Based on the thresholds proposed by Kang et al.4, at speeds of 2 and 3 m/s, however, the shear stresses are 9.3 and 14.05 kPa, respectively, estimating the probabilities of mild and severe injuries. At speed of 5 m/s, the shear stress is considerably larger than 16 kPa (brain tolerance) and fatal injury occurs. The data of shear stress can clearly predict the occurrence of injury.
