Include someone else in the photo who has less chins and less grey hair.
I see no problem taking some selfies with lotta grey hair in it. As for the chin... well, that's a whole different matter. But you can always let grow an astonishing long grey or silverish beard hanging in there to increase the appeal of the selfies.
Ah! just take a peep of how gorgeous this silverish hairy & bearded beast looks like. };)
Hidden the chin, very smart :) Image has been making me laugh, I passed it on to my daughter too and she approves :)
Of course your daughter approves it. Because you will look irresistible with that long grey mane and silver beard waving in the air while riding your bike visiting the pubs. Hahahaha };)
