more than for 30 years

I have been to my home town the other day.
my mother , who is 87 years old this year, lives there alone.
she is very good and powerful.
when i entered into the living room , i noticed an old fan.
it was the fan that i looked at when i was a junior high school student.
wow before 40 yeas ago.
by the way recently in japan we had a problem.
the fan made by sanyo corporation , made more than 30 years ago,

the fan made a lot of troubles, for example the old couple passed away for fire , that was
cause from it. wow my god.
