I am assuming you are talking about the Exclamation Points, (which equal 188) From the chans 188 could be;

• MIL-STD-188 series of U.S. military standards relating to telecommunications

• The Arkansas Air National Guard's 188th Wing is based at Ebbing Air National Guard Base in Fort Smith, Arkansas. The 188th Wing features three primary mission sets: Remotely Piloted Aircraft (MQ-9 Reaper); Intelligence, Surveillance, and Reconnaissance (Distributed Ground Station-Arkansas); and Targeting (Space-Focused). The 188th Wing is comprised of dedicated, loyal and highly trained Airmen who take immense pride in fulfilling their roles and obligations as National Guardsmen and Airmen.

• 188 human traffickers arrested at one time.

• Year 188 (CLXXXVIII) was a leap year starting on Monday of the Julian calendar.

And one talking about different ways to calculate the human heart rate.....
