When enjoying oneself time flies, when not, it goes slow.?

An interesting question, also if you were to smoke dope time would appear slow, and if you were to take cocaine time would appear to speed up. Time obviously doesn't change but when our mind is occupied we don't keep track of time so it appears to p quickly, and when we are boredd we typically look closer at time and it seems to stand still. "a watched kettle never boils". The key is not to slow the enjoyable moment in life but to do them more often, then before you know it you will be old and grey but will of had a fantastic life.
