Mixup of items in airport security checkin

A friend of mine narrated his harrowing experience in a airpot, for no fault of his own. 

After reaching the airport, for security checks, he kept all his electronic items in a tray for X-ray scan and after his physical security check,  he collected his items from outlet platform of the scanner. Then,  he kept all the items in the hand bag, took mobile phone with him, boarded the flight and travelled to the destination. 

While coming out after landing,  he was met with a security person and was asked to show all items in the hand bag. 

To  his surprise, along with his laptop,  chargers, etc one more mobile phone was found which doesn't belong to him.

My friend was questioned and intimidated for this for taking other's mobile phone. My friend explained that he does not how it came in his bag and he collected items only from his tray in the previous airport. Subsequently, my friend learnt that the owner of other mobile phone kept his phone in the tray of my friend during security check in the previous airport which my friend did not realize while collecting and keeping in the bag.

The security in previous airport checked the CCTV footage upto boarding gate, and informed the security of destination airport. 

We have to be careful to guard against other's activities which may affect us as above. 

I also liked about the security aspects in airports about their tracing of missed items as above. 

Policing - not to expect respect

Hazards of phone charging in public places

Sometime ago, the media is flooded with possible data theft by cyber criminals while charging the mobiles using chargers available in public places.

Can be true.

If we have to do it,  we can do so by keeping the mobile switched off.

Personal experience- car driving - microsleeping

Recently,  I was returning from a friend's place by self driving. A friend was sitting in the adjacent seat.

I got up at 0300 hr, started at 0330 hr, picked up a friend,  and drove for 4 hours. After meeting the friend, while returning, I experienced this microsleeping. 

I saw a truck parked roadside during my drive, but didn't make any attempt to move away. Truck is seen, but no action taken. I was awoke. My friend sitting by the side tapped me and I came to full senses and drove the vehicle safely.

I wondered what happened to me, thought like is it sleep paralysis. Later, searched internet and found this state of awoke, but sleeping subconsciously is known as microsleeping.  This arises due to fatigueness, stress, etc.

Remedies are, having good rest before start of journey,  intermittent breaks or short duration rest periods like taking coffee, water, etc.

I sipped water during the driving.
