<p>The cards I found close to useless. The tools in the link from the parent poster, which are actually for pets, work much, much better.<p>And tiny ones are easy to remove with finger nails and some spit. But it requires some skill, do not stress out the ticks while they are attached and be careful to not partially remove it.<p>(Just had to remove 3 ticks on me I failed to spot after a late night walk yesterday, bigger and medium sized ones with tool, the small one with fingernail)<p>edit: and found a 4th one, but a tiny one(nymphe), they don't carry lyme disease as only ticks who bite a infected animal will have it</p>

<p>In general yes, I do climbing and I can say I only do it when I feel no fear, no adrenalin rush. When I feel fear I stop, otherwise danger of accident.<p>But I know a base jumper .. and he only does the jumps if he feels the fear and his kick is to overcome it and feel the adrenalin rush.</p>

<p>The staring you discovered is actually an old meditation technic. Trees are nice for it, but so can be many other things. A burning candle, the setting sun, a cloud, a river  a rock. Important is doing it with intense focus and not get distracted.</p>

<p>Long sidewalks could also be covered with solar roofs for shade, but trees have the advantage that they don't block sunlight in winter without leaves, when sun is nice (in colder climates).</p>

<p>"is be stuck talking with strangers."<p>Then learn not just how to start, but also how to end a conversation. I hated having to do small talk with people - until I learned that I had not to. I now can share something interesting - and then go back to minding my buisness. (If the other person is deaf on their end - strong signals to end a conversation are looking away, turning the body away, opening up ones laptop ... (or put out the damn phone) or put on earphones)</p>

<p>One can have a roadnetwork as primary means of transport .. or a railnetwork. With roads mainly for the last mile.<p>Where society here and now should invest, what direction to go from from here, is totally up to us. What makes the most sense - preferably in the long run.<p>Cars are pretty shitty for long distances. Rubber tyres wear down the road and create unhealthy dust, way more friction and noise than metalwheel on rail. And they can be directly powered with electricity.<p>Not carry a heavy battery around and waste energy with charging and discharging.<p>Or well, have the noise and dirt of combustion engines.<p>Those are all pretty strong arguments to invest at least equally into a well functioning train network.<p>Every car that can be replaced with a train (in the simple often case of a person riding the train not moving his vehicel for himself) is a net profit for society. Cleaner air. Less or allmost no pollution.<p>(The electric trains here next to my home are really silent and still fast)</p>

<p>That is a problem as since the introduction of the ticket there are constant talk from the car lobby politicians to remove it again. So bad for planning for the smaller rail companies.<p>But the biggest problem for the german trains remains the management of DB (Deutsche Bahn). Who are in charge of the network.<p>Who paid themself heavy bonuses all the time, while failing on all the metrics that mattered (they succeeded on making a new useless info page go live, that was the official justification for the bonus).<p>And they could do this, because the job of the ministry of transport was to make it easy for the car industry. And the german train is in theory privatized, in reality not so much.<p>The current ministry might be better though, so maybe something is happening. But I believe it, when I see it.</p>
