If you feel you were ever 'hot' at what point do you accept that you are no longer hot?
I've never thought I was 'hot' so I don't need to come to the hard realisation that I'm no longer 'all that', but some people believe they are a permanent '10' forever and that it will never change.
Most people put themselves above their actual 'level' of hotness if they feel they are (or were, or believe they can become) hot. The sexual market value way of measuring 'hotness' is one common approach but there are many others as 'hotness' is a highly subjective metric.
