This is a funny topic that honestly the SEO insider community has been talking about every now and then - how old is Google's Matt Cutts.
It is almost impossible to find a source online that shows his date of birth. In fact, his Wikipedia profile and an other online profile doesn't mention his age or date of birth. I am sure it can be figured out through a lot of digging.
We do know he graduated with B.S. degrees in both mathematics and computer science from the University of Kentucky in 1995. The average graduation age for a B.S. is likely 23 or so, and that was about 19 years ago. So if you add on another 23 years to that, it makes him around 42 years old.
Someone on Twitter asked Matt outright, how old he is:
@mattcutts my boss and I are having a discussion and we can't figure out how old you are? Google doesn't seem of much use in this instance!

Matt responded in classic Matt:
@PrinceAnthony87 you're only as old as you feel, right? :)

True true. I feel like I am 55 but I am 34.
