Those just got citizenship and became taxi drivers ...... GPS
can help , but eventually you will surrender taxi driving and go
back to China or India ........ become farmer .
Cos u can't forever relying on GPS .
It's all up there in your head .
Your head is the best navigator , the biggest hard disc ,
biggest memory ram . Faster than Galaxy S3 , hahahahah faster
than sound and light .
Go back become farmer , no need to scratch your head with
GPS
