Dear @chbartist
its true that never discovered the technology to trap time or get it back to our life yet, for that- Of Course it may require a time machine or something. Now we can only use our time in most efficient ways so that we could never waste it.
Still, apart from it, you should understand that no one can use his 100% time left in his life effectively. it's only for some kinda machine or something, That's not who we are.
Still its relevant to use our this 'forward moving thing' efficiently also for HELPING OTHERS, so that we could never regret about that!!
