My experiences have been that one can reach some astonishingly high speeds in that event :-) I was once attacked by an entire pack of neglected dogs. It didn't take much effort to outrun them -- they chose to attack at the top of two miles of steep downhill. Yesterday on the MTB we encountered a large group of sheep who bolted off when we came over a hilltop. The large sheep dog was nonplussed about that and came running towards us, growling and snarling. Some teeth showed. I said "nice dog", "good dog". Didn't work ... GRRRROWL. Then I said "perro bonito" - instant smile and tail wag. Later the shepherd called him back, in Spanish. A friend of mine had a Doberman running towards him down a long driveway. French Creek Road in Shingle Springs, CA, where many dogs run free and there are no gates at the end of driveways. So he put on the coals but there was a long uphill section. Not a chance. He heard heavy breathing coming closer and thought "this is it". The Doberman flew by. Way up the hill the dog slowed to a trot and looked back. "Huh? What's the problem? Step on it, dude, let's go!". -- Regards, Joerg http://www.analogconsultants.com/ |

Roger Merriman I feel for you Roger. I have a few trails that I ride a lot. When it's dry those trails are a delight but when they're wet the roots and moss covered stones or rocks make riding a bicycle a real challenge. What makes it more of a challenge is that many of the roots are fairly large and are at angles to the direction of intended travel and that can make keeping the front wheel aligned and the bike upright a very fun exercise. Cheers Yup easy for a bike to follow rocks and what not, though I found that good trail tyres do mitigate this to a extent, surprisingly ability to cling to steep, wet off camber rocks.

Do you get medical advice from a CPA? From whom do you get tax advice, an MD? Mostly from the Internet, after I saw tax pros missing major strategic points. Example: The tax pro of a friend told him only he could contribute to an HSA because his wife no longer worked. Both being over the age limit for catch-up. I told him no, the wife can also contribute $1000 catch-up but it has to be into her separate HSA account. It is called spousal catch-up contribution, hidden way down in the IRS fine print. Well ... oh dang ... the tax pro was wrong and I was right. Then a friend was advised to start a SEP after beginning consulting work. Big mistake. I told him he should go individual 401(k) because the amount of pre-tax funds that can be deferred are massively higher. His tax guy failed to see that, completely missed it, and that had some dire tax consequences which were irreversible. What is the magnesium dosage and how is it determined? I'm going to start taking buckets of the stuff because my back is killing me. My knees are killing me. Basically everything is killing me. The dosage is on the bottle, mainly goes by weight and you have to know your diet. I need two supplement pills per day. Just took them for today. The effect years back was quite profound and it has lasted, no more major flare-ups. -- Regards, Joerg http://www.analogconsultants.com/ |

But how did you discover the basic four Maxwell equations? As I asked, did you stick your finger in a light socket and then reverse engineer the shock to volts and amps? But how did you even learn the basics of that amperage is, what voltage is? Or, staying with the ham radio analogy, how did you learn Morse code? All those little dots and dashes? You just listened and figured it all out? Or even more basic, how did you learn that 2 + 2 = 4? Well actually I guess that you could have come up with groups of 5 so five + five = both hands and 5 + 5 + 5 + 5=both hands and feet?

I suggest that you, in fact, did learn the basics by rote and only than were you able to apply this basic knowledge to solve further problems. -- cheers, John B. |
