How does it feel to be painless....

read an article in Today about 2 indian boys who can't feel any pain...even when they have broken arms and with cuts/bruises...I suddenly had a thought.
Would it be good if we are emotionally painless??? To be exact, it would be great if we can block out certain undesired pain e.g being not heartbroken after a failed relationship, when your dearest friend/loved ones dies. We wouldn't have to go thru the period of remorse, helplessness, regret, depression, loneliness, etc.

Perhaps some ppl would think that would be a cowardly act but not everyone could withstand the pain going through...some can spring back and continue their daily lives, the weaker ones will succumb to depression and sink into oblivion...

Wish there would be a drug or a pill that we can swallow before the pain comes....
