With fuel costs rising and airlines finding more fees to impose(强加，征税) on

travelers every day，airfare isn't getting any cheaper.Since you can't drive to all

your dream destinations，flying is the only way to go sometimes and，undeniably，the fastest.Luckily，there are plenty of ways to find the most affordable fares and

also avoid paying as many extra charges as possible when you plan ahead.

Get the best fare.Airlines put out their fare sales on Tuesday morning，making

this day the best day to book a flight for less.

Fly during the least popular times.Tuesday，Wednesday and Saturday are the

slowest days to fly，which means cheaper deals than the rest of the week.You can

also find reduced rates on early morning flights，since many people don't like to

get up before the sun to get to the airport.Earlier boarding times can also

considerably cut down your chances of getting bumped on an over­booked flight or

delayed because of other delayed flights or mechanical issues.

Choose your seat later.Some airlines charge you to pick your seat when you book

online，adding even more to the bottom line of your ticket cost.If you show up early

on your travel day，you can still get suitable seats.Some of the best seats get held

back until flight day，unless others are willing to pay extra for them ahead of time，so you still have the chance at one of those.

Fly on holidays.You already know that summer is the most expensive time to fly，and even though most other times are more affordable，the days surrounding holidays

can be crazy.Save big if you're willing to travel on major holidays，such as

Thanksgiving and Christmas.

Don't wait until the last­minute to book.Many travelers don't know that there's

a sweet spot for booking and getting the best price on your tickets.Book too early

or too late and you could end up paying more than you need to.The best time to book

is between three months and six weeks from when you want to travel.

If you want to slow aging, you might want to eat less.This finding is good news

if you were a mouse.The researchers studied mice, not people.

John Price and other researchers studied two groups of mice.One group was able

to eat as much as it wanted.The researchers limited what the mice in the other group

ate.Their diet had 35 percent fewer calories than the first group of mice.

Price says the mice with the diet restrictions were “more energetic and suffered

fewer disease.” They were not just living longer but seemed to stay younger for

a longer period of time.

The researchers found that fewer calories slow down a natural mechanism in cells

called ribosomes.Price explains that ribosomes are responsible for making important

proteins in the cells.But with fewer calories, they slow down.This gives the cells

more time to repair themselves.

The researchers say ribosomes use from 10 to 20 percent of the cell's energy

to make those proteins.Price wrote that “because of this, it is impractical to

destroy an entire ribosome” when it starts to break down.However, “repairing

individual parts of the ribosome on a regular basis enables ribosomes to continue
