I rode naked today!

Sort of. I took off after work for my 1 hour ride.A couple of minutes into the ride I realized I forgot my helmet.I started to turn around and said the hell with it.Uneventful ride ,weather is beautiful ,low humidity.Towards the end 2 blocks from the ranch.I sense a car from behind,too close.I hear a familiar voice No Helmet!! Of course it's my wife.Next car is my daughter and son in law.Down goes the window, heh Dad where is your helmet? Never again!

I thought this was going to have something to do with the humidity thread

Happened to me the other day as well. I usually do my (short) commute without a helmet on, so I didn't notice it until halfway through my (long) ride!

My first thought at reading the thread title was, "Eeewwww! Gross."

I rode naked once too, but for me it was starting off on a ride without my gloves. Took about three or four houses down the street when I realized that something just wasn't right. Something was missing, I felt "naked". I did turn around to go home and grab a set of gloves. For sure I want those if I were to fall off the bike.

I think that's a good thing. It means that your helmet fits you comfortably.

I sometimes leave on my bike as early as 5:30 AM. That I would forget to put on my bike shorts is a real possibility.

Some time you just forget. I went for a ride with my wife, who doesn't like going uphill at all. I get to the top of a hill and wait for her to catch up. Then she needs a break at the top of the hill. Break time over, we ride down the back side of the hill. Then she realizes she doesn't have her helmet on. So back up the hill to look for it. No helmet. We finish the ride, and plan to go the LBS for a new one. We get back to the car, open the door, and there it is sitting on the seat.

Glad you didn't crash and die.

Things get a bit hairier when they meet you down the road and you have the helmet on but you forgot the bike...

I've been thinking about this thread, and since you've brought it up, I must say that never in my wildest imagination could I ever conceive of a circumstance where I would forget to bring my helmet, let alone actually start riding without it. I hope this event cues your memory skills.

I ride without helmet every other week, daily commute, just to remind myself that I don't have to if I don't feel like it. I commend OP for making his own decision, rather than turning back because we're "supposed" to always wear one.

Perhaps this?

It may not be universal, but I've noticed that the more consistent I am in wearing a helmet, the more it feels like I have to. The physical risk is so slight that the risk of developing a psychological dependence becomes the greater danger, so I choose at some times to leave the helmet at home. I see it as monitoring for an incipient neurosis (is there any emotional response for example) and as an exercise in mental hygiene.

Yes. This same thing happened to me on the towpath last week. I got all set to head out, put my bandana on (you wouldn't believe how many bugs get in your helmet when riding through the woods by the river)...got about 4 miles down and went to scratch my head through my hole, and realized my helmet wasn't there. I just kept wondering if people were judging me for not having a helmet on.

I did the same thing the other day. Was a couple of miles in before I noticed. Cut between 2 lines of cars waiting for a light and one was a cop car. Thought I was going to get a ticket for sure or something, but nothing.

After being so lucky to have survived the 60s, 70s, 80s, 90s without a helmet....and drinking water out of a hose, I suppose the short, slow, casual rides around town will be ok without a helmet. But I do draw the line at riding in the bed of a pickup at 55mph.

i have walked out the door of the garage without my helmet, but went back. I actually thought this would be a ride without a computer

Haven't worn a helmet in 15 years. Don't see the point of them, frankly.

Let's try to put some qualitative numbers in a crash accident:

You are riding downhill on a paved street and for whatever reason (pothole, small animal, a truck going by, a pedestrian...) you take a spill and hit the sidewalk with top right of your skull. The impact is strong enough to break the bones ...and that's it...You are a vegetable or a cadaver.

Let's assume that the contact surface was 2"x0.5" = 1 square inch (the edge of the sidewalk, crushing your skull).

Had you worn a helmet, the contact patch on your skull would be more like 3" x 2" = 6 in sq therefore the contact pressure would be 1/6th than that of the helmetless.

Moving on, in a collision the kinetic energy of your head K=1/2 mV2 which will increase slightly due to the addition of the helmet mass, has to be absorbed. The kinetic energy absorption is proportional to the load P(t)xΔt. The P(t) is a triangular more or less function and if Δt is the base of the triangle, the kinetic energy is proportional to the area of the triangle.

In the helmeted crash the time Δt increases, because it takes time to crush the styrofoam, before the load is transmitted to your skull. Let's say 3Δt. Since the kinetic energy is the same, this means that the load is further reduced by threefold (more or less independently of the sixfold reduction due to the contact patch). we are at 18-fold reduction of the load which tries to crush your skull.

I told a small lie before. The kinetic energy to be absorbed is not the same. There is energy consumed in crushing the styrofoam. I am not sure how much and how it can be incorporated in a quick qualitative calculation.

Anyway, reducing the load on the skull by 18 times (reducing it to 5.5% of the original) is good enough reason for me. YMMV.

Funny helmet story.

A friend of mine and I commute to work by bike. I leave work first. One day he calls me from work and asks where I hid his helmet and basically is getting torqued because he thought someone hid it and wouldn't tell him. So he goes home totally enraged someone took his helmet. He walks into his house and there is his helmet on the kitchen table. Turns out he drove to work without it on and never realized it. And he's not even 50 yet!

This is pretty one sided qualitative numbers.
As for me the past 5+ years of commuting it should go like this.
"You are riding downhill on a paved street and for whatever reason (pothole, small animal, a truck going by, a pedestrian...) nothing happens, I take no spill, I don't hit the sidewalk with my skull. I get off my bicycle at destination and say to myself that sure was a nice ride." I could "what if" all day long with the best of people. But what I do not do is live in fear or make excuses, which unfortunately is what about 95% of the people do every single day. live in fear and make excuses.
