This woman hasn't smiled for 40 years because she doesn't want wrinkles

50-year-old Tess Christian claims she hasn’t smiled for nearly 40 years because she wants to avoid wrinkles.
 I remember seeing a statement by Kim Kardashian who said she doesn't like smiling too because she's worries about wrinkles.

‘I don’t have wrinkles because I have trained myself to control my facial muscles,’ Tess told MailOnline, 
adding ‘Everyone asks if I’ve had Botox, but I haven’t, and I know that it’s thanks to the fact I haven’t laughed or smiled since I was a teenager. My dedication has paid off, I don’t have a single line on my face.’

While some doctors say not smiling can affect your psyche, others think not smiling works like Botox.

Would you do the same if it would work for you?
