I think you answered your own question. The human nervous system to way too complex to unwire and rewire and the body can't survive without the brain while that's happening.
Same brain, new body? Maybe one day.
Same body, new brain? Probably never. Even if you swap the brain, how do you transfer the mind?
I used to work for a major tire manufacturer.
Changing the diameter of the wheel effectively changes the gear ratio of the drive train. This applies to cars and bikes.
A larger diameter wheel gives more leverage, effectively "gearing down" the vehicle. A smaller diameter wheel gives more RPMs over the same distance, effectively "gearing up" the vehicle.
Bicycles have larger wheels to make them easier to pedal. If you've ever ridden a folding compact bike, you may have noticed the smaller tires make them harder to pedal or have larger gears to compensate.
Car tires have a smaller diameter to reduce material cost. Truck and SUV tires tend to be a little bigger to pad the final torque figure. Tractor tires are huge to maximize torque. Big offroad tires are mostly to give more ground clearance, the extra torque is just a bonus. The reason offroad tires aren't as big as tractor tires is because they still need to fit under a wheel well and because there are height restrictions on street legal vehicles and people occasionally drive a few miles on public roads in their 4x4.
Tread width improves cornering and acceleration performance, to a point, by giving a larger contact patch, which gives more friction, but reduces fuel efficiency and eventually reduces performance. Economy car tires aim for a good balance between braking performance and fuel efficiency. Sports cars aim for a tread width commensurate with the desired performance capabilities; wide enough to put power to the road and stay stable through the corners, but not any wider, so as to keep weight to a minimum.
Bike and motorcycle tires have a curved bottom to give traction while leaning, so this is factored into tread width also.
Tires are part (sometimes the only part) of the suspension of any vehicle. The air in the tire gives cushion. More air means more cushion. Higher tread wall means more room for air. The height of the tread wall is determined by giving enough to soften the ride, but not too much because tires are heavy and additional mass means lower fuel efficiency and reduced performance. Tires are considered "unsprung weight" because they're not supported by the springs of the suspension. When calculating performance, one pound of unsprung weight is equivalent to approximately three pounds of sprung weight, so optimization is important in that area.
Weight capacity, wear rate, and shear strength are determined mostly by the profile design, material composition, and manufacturing process. Diameter and width aren't (usually) adjusted to suit those parameters.
The government wanted more people to go to college, so they offered loans to anyone who wanted to use them to go to college.
Colleges realized loans were getting approved no matter what, so they raised prices because why not.
About 20 rich kids took out loans to attend Harvard Business School, then filed bankruptcy to avoid paying back the loans and because their families are so rich they don't need to borrow money, so 7 years later, bankruptcy rolls of your record and you have a "free" education.
The government looked at that and decided they didn't want anyone else doing it, so they passed a law that says student loans can't be discharged if you file bankruptcy.
So, skyrocketing tuition costs, leads to skyricketing debt, combined with no way to escape the loans, and that's how we have a "student loan crisis."
If what you're saying is true, how do you explain those videos of people playing with Tesla coils while wearing chain link suits?
If the metal gazebo is grounded, and you are not, you'll be protected if lightning strikes the gazebo because electricity will always follow the path of least resistance to ground.
Have you ever seen one of those videos of a guy in a metal suit playing with the lightning from a Tesla coil? Same principle.
Those two sentences are entirely unrelated. Just because lightning will strike wood under some circumstances has nothing to do with whether it's more likely to strike metal.
A more definitive statement would be, "Lightning has been repeatedly observed striking metal objects, and those made of other materials, with equal frequency, provided the objects are of equal height and in the same general location."
Yes. Flip Cup, Beer Pong, and Keg Stands are also real.
