Have you reached an old age? Answer these questions honestly. If you answer "yes" to any of them, you are officially old. See my answer after the photo.
1) You get, not one pair but two pairs of glasses, one pair to cover the reading and computer work, and the other pair to cover the long distance because you woke up one morning and were blind as a bat. Do I really need to see the deer on the mountainside, doctor?
2) When wearing a new exercise bra at the gym and feeling extremely comfortable in it, to notice that after a mile run, the bra is around your neck and your boobs are bouncing freely, causing black eyes and bruised knees, and not knowing that this was happening. (This would not apply to the men folk, except if they witnessed this at the gym, they would laugh out loud and point).
3) When the doctor asks if you're experiencing night sweats, cold sweats, hot flashes or really pissy moods for no reason.
4) When you wish you had a toilet stuck to your office chair so you wouldn't have to get up after a grueling workout with your personal trainer/slave driver.
5) All of the Above.

Answer: 5, All of the above.
