And, here is another example for being practical - I hope Engineers will take this in to consideration...
an old man goes to a drug store to buy some Viagra. Can I have 6 tablets cut in quarters. i can cut them for you said the pharmacist. but a quarter tablet will not give you a full erection. I am 96 years old. I don't want an erection. I just want it sticking out far enough so I don't piss on my slippers.
Now this is something you shouldn't do !! Very Impractical !!
