Do kids feel hotter than adults when its hot and colder than adults when its cold? Why are children more likely to fall sick in changing seasons?
Ask one at a time.: Do kids feel hotter when it's hot? No. Do kids feel colder when it's cold? No. It's an individual thing; some people tolerated higher or lower temperatures better than others.

Prominent veins are generally not a bad sign, especially when present throughout the body parts. ...Read moreSee 1 more doctor answer
