life progress bar

If the average age is 75 years old, there are about 900 months in life, and only a 30x30 grid can be used to display them all. Maybe you have spent 1/3 of them without knowing it, but you think that life is still far away. , Life is like a paintbrush. Use it to write and draw. Unknowingly, you have used it more than half and achieved nothing. Isn't it a pity? Especially when this brush will run out of ink or break for various reasons. How can I create the best painting before it runs out? How to live every day well? I designed this life progress bar today. It was inspired by a blogger on the Internet. The original work used pictures to draw 900 grids.

Take a kitten as an example. If the kitten is 4 years and 5 months old, then 57 squares will be deducted, and one will be deducted every month thereafter. You can intuitively see how much of its life has been spent and how much is left.

There are 4 thin wires connecting the small square to the back plate, as well as the bottom plate
