Watch: How humans came to populate the world over a period of 200,000 years

Keep your eyes on India and China.

China and India have always been neck-and-neck when it comes to being the most populated country. But the two countries owe their numbers to their pasts – reaching back many millennia.

The American Museum of Natural History has released a video showing how humans came to populate the world over a 200,000-year s[pm. It all started with humans migrating from Africa towards the east.

The animation provides a timeline of events and empires in history that explains the changing population numbers. India and China had considerable populations right from the times of Han dynasty and Roman Empire.

But it is only towards the end that the yellow dots suddenly start to spurt across the globe – depicting a stunning spike of humans from one billion to over seven billion in just 200 years.

When did we start parenting our parents?

As our parents grow older, our ‘adulting’ skills are tested like never before.

From answering every homework question to killing every monster under the bed, from soothing every wound with care to crushing anxiety by just the sound of their voice - parents understandably seemed like invincible, know-it-all superheroes all our childhood. It’s no wonder then that reality hits all of a sudden, the first time a parent falls and suffers a slip disc, or wears a thick pair of spectacles to read a restaurant menu - our parents are growing old, and older. It’s a slow process as our parents turn from superheroes to...human.

And just as slow to evolve are the dynamics of our relationship with them. Once upon a time, a peck on the cheek was a frequent ritual. As were handmade birthday cards every year from the artistically inclined, or declaring parents as ‘My Hero’ in school essays. Every parent-child duo could boast of an affectionate ritual - movie nights, cooking Sundays, reading favourite books together etc. The changed dynamic is indeed the most visible in the way we express our affection.

The affection is now expressed in more mature, more subtle ways - ways that mimics that of our own parents’ a lot. When did we start parenting our parents? Was it the first time we offered to foot the electricity bill, or drove them to the doctor, or dragged them along on a much-needed morning walk? Little did we know those innocent acts were but a start of a gradual role reversal.

In adulthood, children’s affection for their parents takes on a sense of responsibility. It includes everything from teaching them how to use smartphones effectively and contributing to family finances to tracking doctor’s appointments and ensuring medicine compliance. Worry and concern, though evidence of love, tend to largely replace old-fashioned patterns of affection between parents and children as the latter grow up.

It’s something that can be easily rectified, though. Start at the simplest - the old-fashioned peck on the cheek. When was the last time you gave your mom or dad a peck on the cheek like a spontaneous five-year-old - for no reason at all? Young parents can take their own children’s behaviour available as inspiration.

As young parents come to understand the responsibilities associated with caring for their parents, they also come to realise that they wouldn’t want their children to go through the same challenges. Creating a safe and secure environment for your family can help you strike a balance between the loving child in you and the caring, responsible adult that you are. A good life insurance plan can help families deal with unforeseen health crises by providing protection against financial loss. Having assurance of a measure of financial security for family can help ease financial tensions considerably, leaving you to focus on being a caring, affectionate child. Moreover,you can eliminate some of the worry for your children when they grow up – as the video below shows.
