[00:51.25]Life must have been difficult when you were
[00:54.00]a kid.Oh,not really.Why do you say that?
[00:57.46]Well,you didn't have many modern inventions.
[01:00.42]Like,you probably didn't have a telephone,right?
[01:03.49]Of course we did!
[01:05.54]How old do you think I am?
[01:07.54]The telephone was invented in 1876.

[01:32.79]Some friends of mine had one.
[01:34.78]But in those days,TVs were really expensive,
[01:37.41]and we couldn't afford one.

[01:41.47]and computers and stuff.
[01:43.42]That's something I do know.
[01:45.70]We learned in school that hand-help calculators
[01:48.73]were invented in 1971 and personal computers
[01:52.52]were invented in 1976.
