Camphor, that lights up bright God's face!
A white round sweet-like substance that smells pleasant and strong to the nose shall attract definitely any child towards it. When it is lighted up, its flame also attracts the child to touch it - but its heat makes the child to retract its hand back! It is our Camphor ('Karpooram' or 'Soodum' in Tamil).

Switching on life with the Pacemaker!
Recently there was news about an Indian-origin doctor implanting inside heart directly a miniature pacemaker, that is leadless - that too without surgery! Pacemaker is a device that stimulates heart when it fails to beat! Without heart's functioning, there is no life at all; so, this life providing device is much more important than anything else.

The artist of the soil, the Earthworm!
I had wondered in my childhood about the straight lines found on the muddy soil: it was raining the previous evening; who would have drawn them overnight! As I grew up, I understood who it is: the lines were drawn by worms, the Earthworms! (term and names: Lumbricus terrestris, Rain worm, Night-crawler, Angleworm, 'Munpulu' in Tamil). Though these brownish worms are found in rainy season, their presence in summer can also be inferred by the mud-disrupted lines on the irrigated farm grounds.

These arrow like flying things are only birds known as Asian Palm Swifts (Cypsiurus balasiensis, 'Panaimara ulavaran' in Tamil).
