Объяснение:

Everybody и nobody относятся к неопределённым местоимениям в единственном числе, поэтому после них глагол ставится как для he/she/it:
everybody understands, everybody has, nobody knows.

Most people, one or two people, some people, a lot of people обозначают множественное число, потому что главное слово — people. Поэтому глагол употребляется без окончания -s:
people believe, people want, people think.

В предложении More than half of us are very worried используется are, потому что речь идёт о части группы людей — us, то есть о множественном числе.
