In prehistoric times the average lifetime was like 22 so 20 would be like 78 today.
In 1776 the average life expectancy was about 35 so 20 would be like 56 today.
In 1870 the average life expectancy was about 40 so 20 would be like 42 today.
In 1916 the average life expectancy was about 41 so 20 would be like 41 today.

So if you want to bitch about the progress of mankind throughout generations, why don't you get off your 75 year old fat ass and go kill a buffalo with a spear, cross the Delaware on a horse wearing a cowboy hat, put on a gas mask and choke to death.

Interesting, the life expectancy today is 80, yet 30 and 40 is still considered old. You hypocritical piece of shit go f**k yourself.

30 and 40 is not considered old. What the hell are you talking about. Hypocritical? Comical. You don't even make sense.

Many of you pieces of shit still consider it that. Even Obama and Janet Napolitano. Pieces of shit!

You do know you're posting on a meme with 20yr olds throughout history right grandpa?

Take your meds and go to bed you crazy fool.

OMG. I suggest you scroll up above, take a re-read of the meme, follow my comments on this meme, realize you're barking up the wrong tree and then....... go away.

You murder me, you shit? Are you having a stroke or something?

What did I miss?

Kid must be 12 or something, given that he thinks 30 & 40 are old and his profuse use of the word of the day: "shit"

It was some crazy shit. Really did seem like the guy was having a stroke. It was that Brilliancy01.

Nope, that’s what the left thinks.

Nope, the left created this nonsense. Janet Napolitano fat bitch

Kids today are so sad...

F**k you communist bitch! You murderous piece of shit!! F**k toy and your mom you lick her weenie you piece of human shit!!

Nope, Obama and that fat stupid bitch Janet Napolitano turned me old before my time. F**k them they are shit f**k them. 60-something old bitch

Kid, 4th grade is gonna be hard on your speshul snowflake ass.

Brilliancy needs to work on effective rebuttal strategy eh?

Looks like the doofus has hit his limit on that front, unless he discovers the fine art of sticking his finger up his nose.

You're not my type.
