Has aged 15 years in only 5 years
This is something that seems to happen with heart throbs. Their good looks make us think they look younger for a very long time (as we generally associate good looks with youth.)
Here is him in 2013:

With his long caramel locks, you'd put him as late 30s to early 40s. Now he looks around 55.
It's sad.
They say thin men show their age after 40 and I think he held off until his 50s.
I think he needs to shave the grey beard, put on a little weight and get in a good place in his life. He seems to be showing his worries.
