One of the gutsiest and greatest boxers of all time, Manny Pacquiao, celebrates his 38th birthday today.

Whenever Pacquiao finally decides to follow through on his proclamations about retirement, the legendary Filipino can look back on a sporting career unlike any other.

Pacquiao is the first and only eight-division world champion, has won 11 major world titles and is the first boxer to win the lineal championship in five different weight classes.

He is also the longest reigning top-ten boxer on The Ring’s pound for pound list.

Coming from a background of extreme poverty, his historic achievements are amplified.

His epic bouts against Oscar De La Hoya and Miguel Cotto will be remembered forever, as well as the long-hyped fight against Floyd Mayweather.

Now combines boxing with serving as a senator of the Philippines.
