Don't smoke, don't drink are the obvious ones... and don't sweat the small stuff... worrying brings wrinkles and a frown! Eat healthy food. Meditation is also good. Smile and laugh as much as you can. Don't over dye your hair.. it can be very ageing. Go grey gracefully if you can. Have a natural look... no heavy make up as it collects in wrinkles and emphasises them!) Invest in a really good quality foundation and use it lightly. Sheseido and Clinique cover without caking. Be happy with who you are. Beauty comes from within.. not from any cream or lotion, despite what all the advertising tells us!!
Things that (sometimes unreasonably) get on your nerves...hopefully lighthearted
