What's the best lens for indoor concert photography?

Faster the better. (That is the lowest f stop number that you can afford.) If you can not afford a very fast lens, I would suggest going with faster film. Push processing slide film can also be an option. (Usually a one stop push does not affect the grain that much.)

As far as length of lens, I would go with a 70-200 or 70-300 zoom lens, if the speed is acceptable. This will give you pretty good close ups if you are not that far away from the stage. If you are up close and personal, that is within the first few rows, a normal lens (50-70mm) should be okay and then you can enlarge and crop to get better close ups. Your fixed normal lenses are also cheaper to get in the faster speeds, f1.4-1.8, than the zoom lenses.

Tips on making a cell phone battery last longer, besides replacing it?

Rechargeable batteries have certain chemicals inside that can hold a charge and regain the charge by adding electricity. Over time, these chemicals (usually nickel and cadmium) lose their potency. The best way to extend their life is to periodically run the battery completely dead, and then recharge it fully. Most take several hours to actually recharge, and if you take them off too soon it can reduce their potency. Always leave your batteries to charge for at least a couple hours, don't always trust what the phone says.

As far as the on/off question, the batteries will keep the current charge for longer if you turn it off, but it shouldn't affect the lifetime of the battery. Vibrate does use more of the current charge, but ditto on the lifetime. If your battery won't keep a long enough charge, the potency is permanently affected and you do need a new battery.

Freezing the battery may work, but it may also cause the battery to explode. Do that at your own risk.

Any advice for a "mature" college student?

It is hard but you can do it. It paid off very well for me.

1. Sometimes you will get very frustrated. If you feel overwhelmed just remind yourself how good it will be at the end.

2. It will be very hard on your kids, but make sure to pay enough attention to them. Remember you are not the only one who is going through a big change.

3. Keep positive attitude. Things always have a way of working out. Especially for those of us who works hard.

4. Don't regret any decision you make. At times you will hesitate. It is normal.

5. Set goals and do your best to accomplish them. even if things change make new plans.

6. Don't give up. Remember everything is for your kids.

7. Take one day at a time.

If riding a motorcycle, and one of the tires blows out, Is there any way to keep the bike upright?

Front flats are bad, but also extremely uncommon. You are safer at speed with a front flat because the centrifugal force of the tire keeps it somewhat in traction. Aim for the shoulder, preferably to grass because you ARE going to crash when your speed drops.

Rear flats are unsettling, but usually recoverable. DO NOT try to accelerate! Your rear end will fishtail if you do - not good on the freeway. You can use your rear brake GENTLY to help maintian directional control as you slow down. I learned these things during the 40 years that I rode.

Remember - Keep the shiny side up!
