Imagine

A friend shared this with me on Linked-in and I decided to share it here:

Imagine being born in 1900.

When you’re 14 years old World War I begins and ends when you are 18 with 22 million dead. Shortly after the “Spanish Flu” kills 50 million. Then at the age of 29 you survive the global economic crisis that started with the collapse of the New York Stock Exchange causing inflation, unemployment and hunger.

Your 39 when world war 2 begins and it ends when you are 45 around 75 million dead in total.

There will be more than 150 million people dead before your 52th birthday when the Korean war begins. When you’re 64, the Vietnam war begins and ends when you are 75.

A child born after 1985 believes his grandparents have no idea how hard life is. A child born in 1995 and 25 today believes that the end of the world is when their Amazon package takes more than three days to arrive or when they don’t exceed 15 likes on Facebook or Instagram.

In 2021, many of us live in comfort, have access to various sources of entertainment at home and often have more than needed. But people complain about everything. They have electricity, phone, food, hot water and a roof over their heads. None of this existed. But humanity survived much more serious circumstances and never lost the joy of life. Maybe it’s time to be less selfish.

Perseverance Rover’s Descent and Touchdown on Mars (Official NASA Video)

NASA’s Mars 2020 Perseverance mission captured thrilling footage of its rover landing in Mars’ Jezero Crater on Feb. 18, 2021. The real footage in this video was captured by several cameras that are part of the rover’s entry, descent, and landing suite. The views include a camera looking down from the spacecraft’s descent stage (a kind of rocket-powered jet pack that helps fly the rover to its landing site), a camera on the rover looking up at the descent stage, a camera on the top of the aeroshell (a capsule protecting the rover) looking up at that parachute, and a camera on the bottom of the rover looking down at the Martian surface. The audio embedded in the video comes from the mission control call-outs during entry, descent, and landing.
