Old Man Uses Paper and Pencils.

As electronic devices become parts of our life, we probabaly don't use paper and pencil as before.
But I feel that my mind is sharper when writing with pencils than when typing with keyboard.
It is probably because I learned with pencil way when I was young.
I hope that my mind stays sharp or sharper with keyboard because of its convenience and speed.
Which is more realistic: adjust my brain to computers OR computers adjust to my brain.
I guess the latter is the answer; therefore, I'll wait the arrival of next generation computers which make me staying sharp or sharper.
