Can the INVISIBLE MAN avoid blindness?

We have been fascinated by the heroics of the Invisible Man.Off and on we keep hearing about the breakthroughs in the field of developing some kind of magic substance that will confer upon us the power of becoming invisible. But as soon as we apply basic physics there is a problem. Retina needs to be opaque to let the image be formed on it before the optic nerve takes the neural signals to the visual cortex.... which simply means that a completely invisible man will be Blind!! Isn't IT SO??

Up hill; walk or cycle

Obviously on a flat road cycling is a more efficient form of transport than walking but when faced with a steep incline I would prefer to walk (despite being a competant cyclist), but surely the mechanisms which make cycling preferable on a shallow incline are still relevent. Am I misguided in my assuption that walking is more efficient on the steep? If not then at what incline does the swich over happen?

astronomical tidal calculation

Is it possible to reliably define the times (for a specific location on earth) when the tidal gravity from astronomical objects (moon, sun etc.) are at their weakest & strongest?

I have considered using sea & ocean tide times, but these factor in unwanted variables, such as ocean currents and coastal water flows, which would invalidate the results somewhat.

I am attempting to define whether any noticeable effects occur from the moon on athletic performance, but need specific times with which to test and compare (hence the strongest & weakest times are my targets).

Why does instant coffee taste different when the water is heated in a saucepan over gas, rather than in an electric kettle? Water source the same; same coffee brand.

Why are dogs and mice attracted to eating crotch of panties?

For women who have dogs or mice in their homes, they have found that some of their dirty underwear have holes in the crotch where a dog or mouse has chewed it up. What is in the vaginal discharge that attracts these animals?

This might sound like a silly question, but this happened to me and I looked online and found that it was not abnormal, and now I really want to know.
